Gold floatation separation
Floatation separation is one of the most common beneficiation methods for quartz gold ore. Mostly, floatation separation makes a high beneficiation efficiency over the sulfide ore of gold with its high flotability. By floatation, both gold and other metals can be separated, and the tailings can be of no value. Floatation separation can be also adoptable for multi-metals recovery like Au-Cu, Au-Pb. Au-Sd, Au-Cu-Pb-Zn-S etc. The floatation separation to get kinds of metal concentrate can help to realize the over-all recovery of mining resource. Moreover, for the indissolvable mineral which can not be dealt with amalgamation and the cyanidation, a conbinated flow sheet covering the floatation separation will be needed. However, there is limitation for floatation separation. When it comes to the coarse gold over 0.2mm or quartz gold without Sulfur, stable floatation froth can not show up after adjusting pulp, and the floatation separation can not work well.

Recently, there is a great progress about the gold floatation separation. And this is represented from 1) innovation of the flow sheet 2) development of new chemical 3) improvement of the design. Multi-phase milling & multi-phase separation is a trend for the gold floatation. Fro overseas gold mine, two or three phases have been adopted while in China, bi-phase milling and bi-phase separation is common to see. And with this design, the gold reciovery rate has been improved by 2-6%. The separation efficiency has been improved greatly after the multi-use of kinds of chemicals. Gold mine in Suichang & Xiangxi use mixture of butyi amine black power and xanthate to improve the recovery rate up by 2-5%.

The final concentrate is not the gold because the gold is enriched together with the sulfide, so usually, few companies make the flow sheet only for floatation separation, and the floatation separation is only part of the flow sheet. At this moment, the single floatation flow sheet happens to some of the small gold mines like Suichang.

Gongyi Forui Machinery Factory is a manufacturer of kinds of gold beneficiation machines like floatation separators, and gold separators and we have machines for test. If 20kgs of samples can be available for us, a free test for you can be done here. And the flow sheet can be designed for you.

Brief introduction to floatation separators:

Floatation separator can be used to separate non-ferrous metal, ferrous metal, precious metal, nonmetallic mineral, chemical fabrication & raw material. All of them can be recycled by roughing, scavenging, selecting and anti-floatation operation.

Working principles of floatation separators:

Floatation separators have the following characteristics: big suction intensity and low power consumption. Each slot can do getter, grouting absorption and flotation to form a floatation circle without any assistant of equipment. It is convenient to change the process with its horizontal distribution. Ore pulp circulates reasonably and can reduce the deposit of the coarse sand to a biggest limitation. The self-controlling device on the surface of the ore pulp helps to adjust. Impeller owns trailing up-down blades. The up-blade brings u p-circulation while the down-blade gives birth to down-circulation.
