What Is the Detailed Technological Process of Gold Flotation?

Jun 8, 2022What should be noted is that for different types of gold ores, the treatment methods are different. For example, when dealing with ore containing single gold ore, coarse and evenly distributed gold ore, multiple grinding and flotation separation are not required. Generally, a grinding-floating process is used for this kind of ore.

Gravity Recoveryof Gold From Within Grinding Circuits Abstract

Gold not only grinds six to twenty times slower than most minerals, it can even flatten and report to coarser size fractions. The long residence time of the gold within the grinding circuit can cause some of the GRG to become non-gravity recoverable due to smearing on to grinding media, mill liners and gangue minerals. This effect is minor as
