  • Milling Mineral Processing Extractives Hub

    Milling Crushing typically takes Run-of-Mine (ROM) ore down to particle sizes ranging from 6mm to 25mm, depending on the type of processes to follow. Crushed ore is fed into Mills in which the ore is mixed with water and may be ground down to a particle size, in the case of gold and copper, of about 75 microns (0.075mm).Toll Milling and Mineral Processing African Pegmatite,Ball Milling is used in the processing of ceramics, paints, coal, pigments, feldspar, and more. In addition to grinding minerals down, a ball miller is often used to mix or blend materials. It can be used for wet or dry milling. Standard ball milling is performed by rotating the chamber around a horizontal axis.
