1. Applications in Metallic Ore Processing
Metallic ores, including sulfide ores, oxide ores, and precious metal ores, require fine grinding to liberate valuable minerals for efficient extraction. Ball mills play a critical role in the comminution process, ensuring optimal particle size for downstream processing.
● Sulfide Ores: Sulfide ores,Copper, Lead-Zinc, Nickel Ores, sphalerite (ZnS) are typically ground in ball mills to liberate sulfide minerals for flotation.
● Oxide Ores: Oxide ores, Iron, Manganese Ores, require fine grinding to enhance magnetic separation or gravity concentration efficiency.
● Precious Metal Ores: Gold and silver ores often require fine grinding to liberate native gold or sulfide-associated gold for flotation or cyanidation.
2. Applications in Non-Metallic Ore Processing
Non-metallic ores, including industrial minerals and construction materials, are ground in ball mills to achieve the desired particle size for applications in ceramics, glass, fillers, and other industries.
● Silicate Minerals: Quartz, Feldspar, Mica, Silicate minerals are ground in ball mills to control particle size for glass, ceramics, and electronics manufacturing.
● Clay Minerals: Clay minerals require fine or ultra-fine grinding to improve whiteness and dispersion for paper, paint, and ceramic industries.
● Special Non-Metallic Ores: Graphite, Phosphate Rock is ground to ultra-fine sizes for lubricants and conductive materials, while phosphate rock is ground for flotation or acid leaching.
