Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls.

SAG Mill Circuit Example – Gold Processing SAG mill circuit example for gold processing [image: (13563)] AG/SAG Mill. AG/SAG mills are normally used to grind runoffmine ore or primary crusher product. Wet grinding in an AG/SAG mill is accomplished in a slurry of 50 to 80 percent solids. 2D and 3D simulations of particles in a SAG Mill

In this sector on Secondary and Tertiary crushing, we will continue the practice of talking about different equipment, the work it does, and the effects of what I call operating variables. These variables are anything that affect the performance of the equipment. Lets begin with an over view of these two crushing stages.

Optimizing Grinding Circuits Abstract This paper outlines the development and implementation of a grinding circuit simulator for BHP Billiton‟s Cannington facility. Steadystate first principles models have been used in conjunction with dynamic process modeling: giving rise to a hybrid model simulator that is valid across a much larger

Crushing and grinding The first stage of the treatment process is the size reduction of the ore particles down to a size giving liberation of the gold/mineral particles. Typically this can incorporate crushing and grinding – however the emphasis needs to be in minimising fines production prior to the gravity concentration stage.

The tailing from the lead flotation circuit is the feed to the zinc circuit. The ability to selectively float the separate minerals depends on the ore, the chemicals, and other factors. Conclusion. Gold, silver, copper, lead, zinc, molybdenum, iron, potash, phosphate, and even sand for glass are often processed …
