What Factors Affect Gold Recovery in a Milling Circuit?
So this has to do with flattening of gold: having it stick onto mill liners, grinding media. Then we’ve got the gravity section or, you know, gravity circuit availability. And then ultimately

Gold Recovery from Gold Copper Concentrates using the
The process developed by Gekko Systems now makes it possible to obtain a high recovery of gold into dore, maximising the benefit obtained by producing a coarse gravity concentrate. PROCESS DESCRIPTION The process involves four steps: Production of a gravity concentrate from the mill circuit.

Optimisation of gold recovery from small scale custom mills
Though gravity concentration process works well with a course fraction, gold recoveries are usually around 50%. Hence, most of the gold is lost to the tailings. As a results, some of the small scale miners in Mozambique and Zimbabwe have modified the processing circuit by adding leaching processes to the gravity concentration tailings.
