What's the Difference Between SAG Mill and Ball Mill ...

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

Stamp Mills for Processing Gold Silver Copper Ore

Stamps are built heavy, made from steel or cast iron heavy enough to pulverize the ore beneath. The stamps are repeatedly raised and dropped onto ore that is fed into the mill, until the coarse ore is reduced to finer material capable of further processing. The stamp mill provided an invaluable need for the early gold miners.

Extracting Gold | HowStuffWorks

To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel-like material then enters rotating drums filled with steel balls.

The easiest way to improve efficiency in mining and to decrease waste products is to decrease a mine's mill cut-off grade. Re-evaluating these grades at each mine will significantly reduce waste. A lower mill cut off grade may decrease the quality of the material, but certain final uses of the material do not need a very pure compound.
