Gold production process by gold flotation machine produced by Derui

Gold has three categories, gold ore (Mountain gold mine, endogenous gold) and gold placer (alluvial, alluvial, beach type, slope deposits type and exogenous gold) and Associated gold (recovery from the non-ferrous minerals )

Gold flotation machine is also known as gold flotation cell and gold flotation tank, which is one kind of ore processing equipment mainly used to separate copper, zinc, lead, nickel, gold, silver, lead and other non-ferrous metals. So, it is also called gold flotation machine and copper ore flotation machine. 

 Gold Flotation machine in factory:

Gold Flotation machine is widely used in gold processing. In China, 80% rock gold is processed by flotation. Flotation process maximizes the enrichment of gold into sulfide minerals. The tailings can be directly discharged.  Flotation machine in gold mine has low beneficiation cost.

Gold Flotation machine is use to process fine gold, sulfide gold-containing quartz ore, multi metal gold-containing sulfide ore and carbon-containing ore.

 Gold Flotation machine working principle:

Mix the mashed rocks with water and necessary reagent in the mixing chute, and inject them to the pulp chute. Lead air to the pulp to make it form large quantities of bubbles, and some mineral particles that are difficult to get moist in water and that are generally called hydrophobic mineral particles will stick on the bubbles and float with the bubbles to the surface of the pulp to form mineralized bubble layer, and some other mineral particles that are easy to get moist in water and that are called hydrophilic mineral particles do not stick on the bubbles but stay in the pulp to discharge the mineralized bubbles containing specific minerals, thus completing the separation process.

Gold Flotation machine Process:

1. Transport the gold ore to gold beneficiation line;
2. Inspect the gold ore, including its hardness, sulfur content, carbon content and other minerals components, then choose the right beneficiation mothed ;
3. Sent gold ore into crushers (jaw crusher, impact crusher, cone crusher, etc.) and grinding mills (ball mill, etc.) to break and make smaller sizes, then tranport the crushed gold ore to gravity separator or flotation machine;

4. Gravity separation is widely used in the rock gold mine, and create good conditions to flotation and cyanidation process, which can improve the beneficiation indicators, improve recovery rate of gold, gravity separator plays a positive role for increasing production and reduce cost;
5. Flotation machine process or a weak cyanide solution to the slurry, this process can extract 93% of the gold and 70% of the silver from the ore. And then the gold is pulled from the solution and attaches to the carbon. Then "strip" the gold from the carbon by washing it with a caustic cyanide solution. And the carbon can beis recycled after this;

6. Pump the gold-bearing solution through electro-winning cells to extract gold metal from the solution by an electrical current;
7. Smelt the gold in a furnace at about 2,100°F. and the molten gold is poured into molds.
8. Send the bars to a refinery for further processing into pure gold.
