What is ore sorting?

Ore sorting is a physical sorting method that uses external forces to separate ore from waste rock by testing and identifying each ore individually based on its physical characteristics. These characteristics, such as color, luster, density, reflection, and refraction, are detected by optical or electrical sensors and analyzed to sort the ore. By using ore sorting technology, it is possible to efficiently separate valuable minerals from the waste rock, leading to cost savings and improved mining operations.

  • There are three main steps to ore sorting:

    1 Identifying Ore
    2 Data Collection by Sensors
    3 Sorting

Sensor-based ore sorting has been used in the mining industry since the 1970s, but recent advances in artificial intelligence, deep learning, machine vision, and image recognition have greatly improved its effectiveness. XRT X-ray sorting technology with deep learning functions, in particular, has the potential to comprehensively utilize low-grade ore resources. This technology can enrich low-grade ore, waste rock, and deemed valueless stockpile waste rock into concentrate with industrial mining value and comprehensive utilization potential. These cutting-edge technologies have opened up new possibilities for the efficient and sustainable utilization of resources.

HPY Technology utilizes both a combined detection method that incorporates a VIS HD dual-sided imaging system and X-ray technology, which can be customized based on the specific characteristics of different ores. HPY has also developed an AI algorithm specifically for ore sorting, called the Wenshu Algorithm. This algorithm applies deep learning theory to the mining industry, allowing for the development of an adaptive ore sorting model that can track and optimize itself in real-time based on changes in ore grade. In complex ore sorting environments, the ore sorting model can adapt its structure to accommodate different characteristics such as ore size, texture, luster, and thickness in order to achieve accurate identification.
