Gold Mine Production Line
Gold Mine Production Line

Introduction:Flotation is a common beneficiation method used by gold concentrators to process rock gold ore. It is often used to process gold-bearing sulfide minerals with high floatability. The flotation process can enrich the gold in the sulfide minerals to a greater extent and the tailings can be directly discarded and the beneficiation cost is low. 80% of the rock gold mines in my country are selected by this process.


Application:Gold flotation process suitable for treating fine particles of gold can be high floating quartz veins sulfide ores containing gold and polymetallic sulfide ores and carbonaceous (graphite) ores.

Process Description

The process diagram of the beneficiation production line is as follows:

Mined ore start with an initial jaw crusher crushing via a hoist to the mining machine into uniform after crushing mill to a reasonable degree of fineness crushing the ore milling by a ball mill. The ore fines ground by the ball mill enter the next process: classification.

A and after graded mineral mixture when passing through the magnetic separator since different than the susceptibility of various minerals magnetic and mechanical forces via the magnetic substance mix separated.

B and fractionated mineral through the mixture passes through the separator through the mixing tube is selected from the mineral to be separated out because it contains large amounts of water subject to the preliminary thickener concentrate and then drying by the dryer i.e. Dry minerals can be obtained.

Gold Flotation Process Flow
Gold mineral flotation normally adopts one stage grinding-flotation process but stages grinding and flotation for ore with uneven distribution.
Grinding Fineness of Gold
For the gold wrapped in sulfide minerals sulfide ore reaches monomer dissociation; but for the gold with gangue grinding fineness should reach gold monomer dissociation. Grinding fineness of minerals is determined by test.
Concentration of Gold Flotation Process
Flotation for large density and coarse particle needs thick pulp whereas for small density and fine particle need dilute pulp.
Other Process Conditions
In addition to the grinding fineness process conditions of gold flotation also includes slurry concentration reagent dosage aeration quantity and flotation time.
