The flotation method is a widely used technique for the recovery of gold from gold-containing copper ores, base metal ores, copper-nickel ores, platinum group ores and many other ores where other processes are not applicable.

Gold Flotation Production Line 

Process Introduction

Flotation is the most widely used method in gold processing plant to deal with rock gold. It is mainly used to deal with gold ores with high floatability.

Flotation process maximizes the enrichment of gold into sulfide minerals. The tailing can be directly discharged. In China, 80% rock gold is processed by flotation for its low cost.

Application of Flotation 

Whether the gold ore is applicable to the flotation method depends on whether it has better floatability.

For simple ore just containing gold, and the granularity of gold is uniform, and high floatability, simple grinding and flotation process is always the best solution.

If the ore contains some particle gold, gravity or amalgamation operation will be set in the grinding and classification circuit.

Gold is usually concentrated in mineral concentrate by flotation if the gold is contained in polymetallic ore.

Process description

In the process of flotation, the following steps are included: crushing and screening, grinding and classification, flotation, thickening, filtration, etc.

The common equipment includes: jaw crusher, cone crusher, belt conveyor, vibrating screen, ball mill, spiral classifier, flotation cell (or flotation column), slurry pump, thickener, ceramic filter and so on.

Common flotation agents include: collecting agents, foaming agents, adjustment agents

The main factors affecting flotation include: grinding fineness, slurry concentration, dosage of agents, volume of aeration, flotation time and so on.
