Have you ever wondered how to separate white feldspar from white quartz? If so, AI optical sorting machines offer an amazing solution.   With these advanced machines, separating white feldspar from white quartz has never been easier. Here's how it works:   Before production, build a model for white quartz and white feldspar separately using 10,000 images with different angles. The machine needs 30 minutes for self-training to learn the properties.   Processing:     Optical sorting machines utilize CCD sensors to detect subtle differences in the optical properties of minerals. The machine can distinguish between white feldspar and white quartz due to their slightly different optical properties.    The minerals are fed into the machine and scanned by CCD sensors as they pass along a high-speed conveyor belt at a rate of 3 meters/sec. The sensors analyze each particle in real-time for differences as small as 0.02 mm².     The machine then separates the white feldspar from the white quartz using pre-programmed settings with the MINGDE algorithm. The system transforms optical signals into electronic signals and orders air valves to inject the white feldspar into separate collection bins. This process results in complete separation of the minerals. If you work in a related field, AI optical sorting machines are worth considering. They revolutionize the process of separating white feldspar from white quartz and are also useful in many difficult mineral sorting projects that traditional color sorters cannot handle, making our lives easier.By utilizing these modern and innovative machines, we can save time and resources while ensuring that only the desired minerals are sorted. This is a significant win for sustainability!

  Imagine being able to efficiently and effectively separate pure white calcium carbonate from a mixture, saving time and resources with the help of an MINGDE ore color sorter.   The process is simple: 1) Preparation:calcium carbonate raw materials go from the feeder into the MINGDE ore color sorter 2) Calibration:set the sorter to recognize the specific color of calcium carbonate 3) Sorting:the CCD line-scan camera is used to differentiate unwanted stones from pure calcium carbonate based on a subtle color difference of 0.02mm².As the stones pass through the sorter on a high-speed conveyor with a transmission speed of 3 meters per second, the CCD sensor identifies and separates the unwanted stones in real-time. The output is 20 tons per hour for 1-3cm particle size and 40 tons per hour for 3-8cm particle size. 4) Collection: collect the separated high-brightness calcium carbonate particles for further processing and use.   Utilizing an ore color sorter not only allows for efficient separation but also reduces the need for manual sorting, significantly streamlining the production of calcium carbonate.   By adopting innovative technologies like the ore color sorter, we can revolutionize the way we separate valuable materials from their mixtures, improving productivity and sustainability. Let's embrace progress and unlock the full potential of minerals!  

Did you ever wonder how ore sorting works?  Let's delve into the fascinating techniques used in this process!    Optical sorting: This technique relies on sensors to identify differences in the optical properties of ores. It uses cameras or lasers to analyze size, shape, color, and lusters, enabling the system to separate valuable ore from waste efficiently.    X-ray transmission: X-ray technology is used to determine the atomic density of each particle to distinguish between low-density waste and high-density valuable ore. This technique is often employed to sort minerals like gold,copper, coal, and other dense materials.    Magnetic separation: As the name suggests, this technique uses magnets to separate magnetic materials from non-magnetic ones.This method is commonly used in iron ore processing to remove unwanted magnetic material and produce a concentrate of higher iron grades.    Gravity separation: Based on the principle that different materials have different densities, gravity separation techniques use centrifugal force or water flow to separate valuable ore from gangue (waste). It's widely utilized in mining operations to separate gold, tin, and other heavy minerals.    These techniques are revolutionizing the mining industry by improving both efficiency and sustainability. 

Hey everyone! Today, let's dive into the fascinating world of mineral sorting and learn about the intriguing process behind it!   Mineral sorting is a vital practice that allows the separation and categorization of different types of minerals based on their composition. It helps in optimizing mining operations and extracting valuable resources efficiently. So, how does it work? Let's find out!   The first step in mineral sorting involves collecting samples from the mining site. These samples are then passed through a series of processes that use cutting-edge technology to analyze their properties.   One widely-used technique is optical sorting, which uses sensors and high-speed cameras to analyze the minerals. Such as color sorter,it distinguish mineral surface by color differences,if need process more complicated minerals,such as sort out white feldspar from white quartz,or impurities surface is quite close to concentrate,then our AI intelligent sorting machine can perfectly solve sorting problesm by examines their color, shape, luster,quality and more than 200 surface features.   Another approach is X-ray transmission sorting. This method utilizes X-ray beams to penetrate the minerals, and by measuring the differences in X-ray absorption, it can identify the specific elements present in each mineral.   Once the analysis is complete, sophisticated sorting machines use air jets, conveyor belts, and other mechanical aids to separate the minerals based on their identified properties.   By separating valuable minerals from waste materials, mineral sorting significantly reduces processing costs and enhances resource recovery. Moreover, it minimizes the environmental impact by reducing the amount of waste generated.   Mineral sorting technology has revolutionized the mining industry and played a pivotal role in sustainable resource management.

Ore Color sorting machines are innovative pieces of equipment that play a vital role in ore industries, the machines utilize advanced technology to sort various kind of minerals, such as quartzs, calcites, calcium carbonates,etc., based on their color. But have you ever wondered how these machines actually work? In this section, we will delve into the working principle of a ore color sorting machine and explore the intricate process behind its functionality.   The operation of a color sorter machine can be categorized into four distinct systems: the Feeding System, Optical System, Control System, and Separation System. Feeding System: Object Introduction: Objects to be sorted are fed into the color sorter machine using a hopper or conveyor system. Even Distribution: The system ensures even spreading of objects in a single layer for optimal visibility during sorting. Optical System: Illumination: A suitable light source, evenly illuminates the objects for consistent lighting conditions. Sensing and Imaging: Optical sensors or cameras capture images of the objects, with monochromatic or multispectral options depending on color detection needs. Control System: Image Processing: Captured images undergo processing using specialized software and algorithms to analyze color information and extract relevant features. Color Classification: The system compares extracted color features against predetermined criteria, classifying objects into distinct color categories or grades. Separation System: Sorting Mechanism: Once objects are classified based on color, a sorting mechanism is activated to physically separate them into different streams or containers. Ejection or Diversion: In case an object is in the wrong color category, the sorting mechanism diverts or removes it from the main stream to ensure the final output contains only objects of the desired color. Collection and Disposal: Sorted objects are collected in separate containers or conveyed to different locations based on color. Rejected objects are typically disposed of or directed to a separate waste stream. These four systems work collaboratively to enable rapid and continuous high-speed sorting operations, with the precision and efficiency of the color sorter machine dependent on the quality of each system's components and the coordinated control of their functions. It's worth noting that specific details may vary among different types and models of color sorter machines, and advanced systems may incorporate additional features based on specific application requirements.

Industrial silicon production is based on silica as raw material and carbonaceous raw material as reducing agent, which is smelted by electric furnace. Among them, industrial silicon is mainly used as raw material for polysilicon, monocrystalline silicon, silicon alloy, and organic silicon, with applications in aerospace, new energy, high-purity semiconductor and other industries, and the demand is increasing year by year. Industrial silicon in the process of smelting refined silicon in the average refining 1 ton of silicon water produces about 100 kg of silicon slag, so the number of industrial silicon slag produced each year is huge, for a long time silicon slag is used to pave the road or as a waste pile, not only occupy a lot of land resources, but also bring a series of environmental problems. At the same time, industrial silicon slag contains more than 15% of monomeric silicon, which is not utilized, resulting in a waste of silicon resources and bringing great economic losses to enterprises. In addition, there is also heavy adulterated silicon material in silicon waste that has been mixed with impurities such as B, P, Ga, Al, etc. In order to enhance utilization, it is also necessary to sort out the available silicon.   Industrial Silicon Smelting   Currently. For industrial silicon slag and mixed silicon waste processing methods are mainly manual sorting, re-sorting process, electromagnetic induction melting or back to the furnace re-refining way, which manual sorting by crushing large silicon waste, from which large particles of industrial silicon for recycling, the overall sorting efficiency is low, after sorting there are more high content of industrial silicon can not be recycled; re-election process requires the silicon slag grinding to a few millimeters, the process is complex, and also waste a lot of water. Also wastes a lot of water, and the separation effect is relatively general; electromagnetic induction melting or furnace melting, because of high energy consumption and silicon slag viscosity, it is difficult to directly separate out.   The existing recycling process of industrial silicon have certain problems, but the application of the latest sorting technology of artificial intelligence sorting machine, in the sorting can replace the existing silicon slag sorting process, to provide a simple and efficient sorting method, and enhance the industrial silicon recycling rate in silicon slag. The silicon slag only need to crush, Use artificial intelligence machine sorting directly, in the silicon slag recovery of industrial silicon sorting precision, sorting effect, sorting efficiency, recovery rate, recovery costs are better than the existing silicon slag sorting process.   The main working principle is that the silicon slag is crushed and dissociated, and the difference in surface characteristics between the slag and industrial silicon is used to identify good and bad materials through photoelectric sorting technology,Optical sorting machine, and the good and bad materials are sorted out through the control system controlling the spray valve, so as to achieve the sorting separation of silicon slag and industrial silicon.     Before sorting   After sorting   At the same time, the artificial intelligence sorting machine has a great improvement in sorting compared with the ore color sorting machine, which can only judge good and bad materials based on color. In the silicon slag sorting, there is a coexistence of good and bad materials, small color differences, it can not identify the good and bad materials by color, artificial intelligence machine will not worry about this problem, through the identification of multi-dimensional characteristics of silicon slag,it establish the models, accurately identify materials with good sorting effect. So as to achieve the purpose of high-efficiency recycling of industrial silicon and increase the economic benefits of enterprises.   As a high-tech enterprise specializing in industrial ore sorting, Mingde Optoelectronics has mature technology accumulation for solving all kinds of industrial ore sorting problems and bulk ore sorting system, and the product application scope covers talc, fluorite, wollastonite, potassium feldspar, barite, quartzite, calcite, calcium carbonate, magnesite, lithium pyroxene, phosphate ore, gold ore, pebbles, quartz sand, coal gangue, vanadium ore and nearly 100 kinds of metal and non-metal. We have strong technical advantages in the field of ore sorting. The Preconcentration and discarding sorting machine will achieve the rapid accumulation of wealth.   Edited by Jacky 

Lead zinc ore refers to the mineral resources rich in metal elements lead and zinc. In nature, lead and zinc often coexist, and are also associated with other metal ores and gangue ores. The metal ores mainly include brass, pyrite, etc. The gangue ores mainly include quartz, calcite, fluorite, barite, dolomite, etc. According to oxidation, it can be divided into oxidized ores and sulfide ores. Because lead-zinc ores have strong sulfur affinity, most lead-zinc ores in nature are sulfide ores. The main application fields are machinery, military, metallurgy, chemistry and medicine. The domestic lead and zinc mineral resources are relatively rich, which are characterized by wide distribution and high concentration of mineral resources in 27 provinces, cities and districts in China. From the perspective of enrichment and existing reserves, China's lead and zinc ores are mainly distributed in Inner Mongolia, Gansu, Hunan, Yunnan, Guangxi and Guangdong, accounting for 64% of the national lead and zinc ore reserves; Large and medium-sized deposit stations have high reserves and complex ore types. The reserves of lead and zinc in large and medium-sized deposits account for 72% and 88.4% respectively. There are few single type lead or zinc ores, and the ore types are relatively complex, mainly including lead zinc ores, lead zinc copper ores, lead tin ores, lead antimony ores, etc; There are many poor ores, few rich ores and few easy beneficiation. According to statistics, the domestic lead and zinc ores are mostly of 5% - 10% grade, and those with a grade higher than 10% only account for 15% of the total storage, while the foreign lead and zinc ores have a higher overall grade, most of which are more than 10%. The types of lead-zinc deposits in China mainly include granite type, skarn type, porphyry type, marine volcanic rock type, continental volcanic rock type, carbonate rock type, mudstone fine clastic rock type and glutenite type. In terms of beneficiation process, the lead-zinc ore is mainly flotation, and gravity concentration is also used. At the same time, the internal distribution of lead-zinc ore is uneven. There are different separation processes for each ore. The common separation processes of lead-zinc ores in China mainly include preferential flotation, mixed flotation, full mixed flotation, heavy medium pre separation, heavy medium pre separation flotation gravity separation combination, etc. floatable flotation and asynchronous mixed flotation. The above sorting methods of lead and zinc ores belong to conventional traditional separation methods, but at present, China's lead and zinc industry is mainly faced with several problems. The contradiction between industrial sustainable development and ecological environment protection is mainly reflected in China's long-term high demand for lead and zinc ores, driving the rapid development of lead and zinc industry, causing certain impact and damage to the ecological environment, and the low comprehensive utilization of lead and zinc resources, Especially in the aspect of valuable associated gangue, at the same time, strict prevention of heavy metal pollution has become an insurmountable red line in the lead and zinc industry. The way of scale, volume and extensive development in the lead and zinc industry has not met the development needs at this stage. At this stage, it is necessary to change to a circular, low-carbon and green direction. Another important reason is that the production cost of lead-zinc ore has risen and the product price has fallen, and the cost rigidity has risen - the equipment has low operating rate - the supply is relatively surplus - the price has low volatility - the benefit has been marginalized ". At the present stage, the requirements for lead and zinc ore mining and beneficiation are to meet the needs of social development, improve the comprehensive utilization of resources, reduce production costs. Green and sustainable development is the new trend of the industry, especially in the continuous use of lead and zinc beneficiation process, which is obvious. For some lead and zinc ore beneficiation stages, we can fully take measures to increase the economic benefits of the mine, save the beneficiation cost and reduce the tailings disposal capacity, It also meets the development needs of green mines. The main plan is to enrich the grade of lead-zinc ore in advance, pre dispose the waste tailings, and reduce the processing capacity of grinding flotation raw ore, mainly using the photoelectric separation equipment ore separator. There are mainly two types of ore separation equipment suitable for the separation of lead and zinc ores. One is the Mingde Optoelectronics artificial intelligent ore separator, which establishes a multidimensional three-dimensional model of ores through the surface characteristics difference after the lead and zinc ores are broken and separated, and identifies the good and bad materials, so as to achieve the purpose of grade enrichment. For example, lead and zinc barite, lead and zinc fluorite ores, etc., the expected beneficiation effect can be achieved through the artificial intelligent ore separator. The second one is X-ray intelligent ore separator, which mainly uses X-ray to project lead-zinc ore and identify the good and bad materials according to the difference of ore density, so as to achieve the purpose of enrichment. The above two ore separators can meet the development needs of the lead-zinc industry at this stage.   Among them, Mingde Optoelectronics focuses on the field of ore separation and digital color separating machine. It has accumulated rich experience and technology in ore photoelectric separation and precipitation. The four series of products designed and produced not only have a development prospect in the lead and zinc industry, but also have a large application space in other ore separation and beneficiation fields. At this stage, the application scope covers the metal and non-metallic fields, such as fluorite, talc, quartzite, barite, K-feldspar, calcium carbonate, magnesite, gold mine There are nearly 100 kinds of ores such as high crystal silicon, copper, iron, vanadium, phosphate rock, coal and gangue.
