Crusher Circuits In Gold Ore

The gold ore straight from the mine gets fed into a jaw crusher first. This big machine breaks down the huge rocks into smaller pieces, usually around 100-200 mm in size. After that, the crushed ore moves to the secondary crusher, which is usually a cone crusher. Here, it gets crushed even more, down to around 10-50 mm.

Redalyc.Circulating load calculation in grinding circuits

In closed circuit grinding, as the example depicted in figure 1, the circulating load is, in some cases, 400 times the ratio of the weight of the hydrocyclone oversize returning to the reduction machine to the weight of new feed entering the circuit in the same time interval. For better understanding of the overall circuit operation the correct

Finding the Ore Liberation Size For Gravity Circuits: Sizing …

Tune the grinding circuit to only grind fine enough to attain the commercially-viable liberation size. If gold is found in the 200-300 or <325 mesh fractions, it is likely gold-bearing sulfides or free milling gold <~400 mesh. This gold is not practical to recover via gravity concentration, so flotation or leaching could be used. Additional notes
