Milling Mineral Processing Extractives Hub

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). The fine, powdered ore emerges from the mills mixed with water in a thin, wet paste called Pulp or Slurry.

ASARCO » Milling

The ore is ground into a fine powder by large rotating mills. The two types used in the Mission South Mill are called SAG (semi-autogenous grinding) mills and ball mills. SAG mills use larger pieces of ore to break up the smaller pieces (autogenous — does it by itself). The larger pieces break down as well.

Factors Influence Ore Grinding Mill Efficiency - JXSC

2019-5-10  The throwing motion medium is used to smash large ore, and the medium of falling movement mainly plays the role of grinding. The filling rate of the fine grinding mill is about 5% lower than that of the coarse grinding. The motion state of the medium in the mill is related to the medium filling rate.
