Gold Extraction Machine-Gold Ore Beneficiation

Application of Gold:

Gold is a precious and luxury metal extracted from gold ore to make treasure and ornament. The gold concentrate can be melted and cast into almost any shapes to make jewelry. There are numerous industrial applications for gold. As well, many electronics and medical devices need gold to conduct electricity and resist corrosion.

Gold Extraction and Beneficiation:

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.
