IV. Types of Ore That Can Be Separated

● Non-metallic minerals: Quartz, calcite, potassium feldspar, dolomite, fluorite, barite, gypsum, kaolin, calcium carbonate, silica, coal gangue, and over a hundred other types.  
● Metallic ores: Tungsten ore, lithium ore, molybdenum ore, aluminum ore, tin ore, copper ore, gold ore, hematite, manganese ore, and others.  
● Others: Pebbles, glass granules, industrial salt, chemical granules, waste glass, metallurgical silicon, brick and concrete, recycled resources, and the like.

V. Particle Size Range for Sorting

● Scope of the standard: From 16 mesh (approximately 1 mm) to 50 mm (5 cm), supporting simultaneous sorting of mixed particle sizes.  
● Mixed sorting interval: 0.1–0.5 cm, 0.5–3 cm, and 3–5 cm can be mixed and sorted without prior grading.  
● Extended Compatibility: Customized models can handle large particles ranging from 0.5 to 8 cm.

VI. Sorting and Recognition Dimensions

● Color dimension: RGB three channels plus multispectral (infrared/ultraviolet) imaging, enabling the detection of micron‑scale color differences and the differentiation of foreign particles in white, yellow, black, red, brown, and other hues.  
● Texture dimension: AI deep-learning algorithms capture surface textures, fractures, and inclusions, enabling the identification of homogeneous yet color‑different impurities.  
● Shape dimension: “Color sorting + shape sorting” dual-mode, removing deformed, broken, and impurity‑contaminated particles.  
● Spectral dimension: Multispectral fusion sensing overcomes the limitations of conventional RGB imaging, enabling the detection of hidden impurities such as biotite in feldspar and rust.
