2012-7-1 · Of the limited studies that have been performed on flash flotation systems, some are focussed on the comminution circuit, or provide qualitative information on circuit performance at best, whilst others are focused solely on the precious metal behaviour and compare the results of the gravity gold recovery tests to flash flotation performance ...

Sulphide Flotation - an overview | ScienceDirect Topics

Many copper–gold concentrators have a combination of flash flotation and gravity separation in the milling circuit to enhance overall free gold recovery. The reason for the inclusion of gravity separation at these concentrators is that the coarse free gold is not recovered effectively in the flash flotation cell.

2013-11-1 · Although there are recognised laboratory flotation tests to predict the behaviour of ore in a sulfide flash flotation circuit, the behaviour of free gold recovery in flash flotation remains poorly understood, particularly when in competition with a gravity recovery circuit (Laplante, 2005). Therefore, the primary goal of this research is to ...
