Gravity Recovery of Gold From Within Grinding
2020-9-9 Batch centrifugal gravity concentrators, which produce very high concentration ratios, have become the devices of choice for recovering gold from within grinding circuits. These are usually installed in the mill discharge, cyclone feed or the cyclone underflow streams where a fraction, typically 10-40%, of the stream is treated by the gravity circuit.

GRAVITY CONCENTRATION OF GOLD FROM CYCLONE
2019-10-1 Many process engineers view gravity concentration in gold grinding circuits as a nuisance and asecurity risk. In part, this is probably due to the chequered history of enhanced gravityconcentration, and the inability to predict the impact a gravity circuit will have on overallperformance of a given plant. In the past, there have been many failed attempts to produceequipment of this type. Today, there is a choice of suppliers of reliable, proven machines and thephysical principals behind their operation are becoming better understood. Further, today'smachines are sufficiently reliable and automated that they can be placed in a secure enclosure. It isnow necessary to consider gravity concentration not as a nuisance that must be tolerated but as apowerful tool to increase productivity. Although more work is required to predict precisely theperformance of a gravity concentration circuit before a plant is constructed, we can predict whethera plant will derive some benefit from gravity concentration. Unfortunately, for the reasonsdiscussed herein, current practice does not do justice to gravity concentration.Coarse GoldIt may seem trite to point this out, but coarse gold

Gravity Concentration an overview ScienceDirect
Even if the actual V lg was 57% instead of 60%, the low gravity concentration would be 34% volume. In most cases the decision to continue running the mud cleaner would not be affected by this inaccuracy. Even if the barite in the discard exceeded the low gravity concentration, the benefits of removing those larger solids will be evident. Accurate results, of course, can be obtained by retorting the solids; but
