Nowadays,as the world's largest consumer of mineral resources, China's demand for minerals has shown explosive growth. However, the bottleneck of domestic resource reserves and quality has forced Chinese companies to look overseas.

In this process, the fragility of cross-border supply chains is gradually exposed, especially the high transportation costs and inefficient mineral processing links, which have become key challenges restricting resource security. In this context,intelligent mineral processing equipment enterprises represented by Mingde Optoelectronics are reconstructing the cost logic of the global mineral supply chain through technological innovation in pre sorting.

一、Transportation Cost Dilemma: Dual Squeeze of Inefficient Mineral Processing and High Logistics Losses

Overseas mineral development generally faces the "raw ore transportation trap": due to the lack of modern beneficiation facilities in mining areas, a large amount of low-grade ore is directly transported without pre-treatment，this way will not only does it increase shipping costs, but it also causes hidden losses in areas such as port storage and tariff collection.

Traditional solutions rely on manual sorting or simple screening, which is inefficient and costly, and urgently requires new technologies to break through.

二、Mingde optoelectronics sorting:rebuilt the cost model of ore mountain resource

Mingde Optoelectronics' intelligent sorting equipment, through high-precision sensing and AI algorithms, can quickly achieve ore pre sorting on the mining site, reshaping supply chain efficiency from three dimensions:

Transportation cost compression: The equipment can identify the differences in color, texture, texture, shape, luster, density, etc. between ore and waste rock through visible light and X-ray based on the characteristics of the ore. The sorting accuracy is over 95%. Taking a manganese mine in South Africa as an example, after using Mingde equipment for pre sorting, the ore grade increased from 28% to 42%, the amount of ineffective impurities transported decreased by 60%, and the cost of single ship manganese ore transportation decreased by 22%.

Mineral processing efficiency has increased significantly: the processing capacity of a single equipment can reach 50-100 tons/hour, which is 20 times more efficient than manual sorting. In the mining area of Vietnam, the manpower demand for the Mingde sorting line has decreased by 80%.

Breakthrough in Resource Utilization: The AI dynamic learning system can recognize mineral particles larger than 0.5cm. If oxidized copper ore is applied, the average grade of the ore can be increased by 40% -60%, and the resource recovery rate can be increased by 15 percentage points.

三、Global Practice: Empowering Supply Chain Resilience with Technology

Mingde Optoelectronics' solution has been validated for its value in multiple key mineral supply chains:

Southeast Asian Limestone: Deploying photoelectric sorting equipment in Indonesian mining areas can effectively select concentrates, secondary ores, and impurities from limestone, increasing revenue by more than 100 yuan per ton.

Afghan Quartz Mine: The Afghan quartz mining area uses Mingde equipment to pre throw tailings, throwing out 25% impurities and increasing ore value by more than 30%.

Vietnamese white silicon and white potassium ore: Vietnamese mines remove white potassium from white silicon through pre sorting, and the selected concentrate can be directly processed for high-end board sand use.

The more profound impact lies in the innovation of supply chain models: pre sorting equipment enables the front-end of mines to produce high value-added semi-finished products. For example, the fluorite ore in Outer Mongolia is sorted and directly outputs concentrate with a grade of 90 or above, with a transportation volume of only 3/5 of the original ore, and can be directly used as terminal products upon arrival at the port.

Therefore, according to industry estimates, if China's overseas mines fully promote intelligent sorting technology, it can save logistics costs of over 12 billion US dollars annually and release 300-500 million tons of ineffective transportation capacity. This change is not only related to the efficiency of enterprises, but also an important support for the strategic security of national resources.
