Application Progress of Color Sorter Multispectral Technology in Global Ore Sorting Field
2025-08-29The global ore sorting industry is undergoing a technological revolution driven by Color Sorter multispectral technology, which has broken the limitations of traditional sorting methods relying on manual or single-color detection. Unlike Rice Color Sorter or Grain Color Sorter that focus on organic material purity, ore-specific Optical Sorter with multispectral imaging can capture invisible spectral signatures of minerals, enabling precise identification of ore grades and impurities.
In iron ore sorting, multispectral Color Sorting Machine distinguishes hematite from gangue by analyzing their unique spectral reflectance, increasing concentrate recovery rates by 15-20% compared to conventional methods. For rare earth ores, the technology accurately detects trace rare earth elements in raw ore, avoiding the waste of valuable resources that traditional sorters often miss. Even in complex gold ore sorting, multispectral Color Sorter identifies gold-bearing quartz veins by sensing subtle spectral differences, reducing the cost of subsequent smelting.
Major mining regions like Australia’s Pilbara and South Africa’s Witwatersrand have widely adopted this technology. Leading manufacturers have upgraded their Optical Sorter lines to integrate 8-16 spectral bands, enhancing adaptability to different ore types—from copper ore to lithium ore. This progress not only improves sorting efficiency but also aligns with global mining’s sustainability goals by reducing energy consumption and environmental impact.
As ore deposits become increasingly low-grade and complex, multispectral Color Sorting Machine has become a core equipment for modern mines, driving the transformation of the global ore processing industry.
