The main purpose of ore sorting is to increase the concentration of useful minerals and reduce the content of useless minerals (usually called gangue) or harmful minerals, so as to make the ore more suitable for subsequent smelting or processing.Photoelectric sorting has the following functions：

1. It can improve the utilization rate and grade of ore. Photoelectric sorting can separate useful minerals from gangue minerals in ore. The concentration of useful minerals is increased, thereby improving the overall utilization rate and economic value of ore.

2. Photoelectric sorting technology can quickly identify useful minerals and waste rocks in ore, and achieve rapid separation through precise control of actuators, thereby improving the overall beneficiation efficiency.

3. Reduce production costs. Compared with traditional physical beneficiation and chemical beneficiation, the main energy consumption of photoelectric beneficiation is electricity consumption, and the cost of beneficiation per ton is low. Electric sorting can remove waste rocks and impurities in ore at an early stage, reduce later transportation costs and material and energy consumption in subsequent processing, thereby reducing production costs. Improve market competitiveness

4. Provide high-purity raw materials. Photoelectric sorting not only increases the proportion of useful components in ore, but also reduces the impurity content, providing high-purity raw materials for smelting and other industrial processes, thereby improving the quality of the final product.

5. Photoelectric sorting technology can realize the comprehensive utilization of low-grade resources, reduce the requirements for ore mining grade, increase the overall resource reserves, and extend the mining life of the mine.

6. Photoelectric sorting can reduce the generation of tailings, and reducing the amount of tailings helps to reduce the impact on the environment and reduce the risk of water and soil pollution.

With the introduction of technologies such as artificial intelligence and big data analysis, the intelligence level and adaptability of the photoelectric sorting system have been improved, enabling this technology to better cope with the challenges of various ore sorting.
