Gold loaded carbon is processed by stripping and electrowinning to get gold slime. Pregnant solution is precipitated by zinc to produce gold slime. The gold mud is smelted to cast gold ingots after a series of processing: pickling, separating other metals, washing, filtering, drying, etc. The purity of the merging gold ingot can reach over 97%

In short, the gold refining process calculates the amount of pure gold and alloy metals. Karat is a measurement unit to indicate how much pure gold is present in an alloy. For instance, 24-karat gold indicates pure gold, and 18-karat gold indicates 18 parts of pure gold and 6 parts of another alloy. Gold is not available in its purest form. It

At many operating gold plants, an increase in gold dissolution is observed when a leach slurry is transferred from one type of process equipment to another (i.e., between leach tanks, thickeners, filters, pumps, and pipelines). This is explained by the different mixing mechanisms in the different equipment, coupled with other factors, such as changes in slurry percent solids, changes in

Gold extraction process is a combined process of various gold extraction methods (amalgamation, gravity separation, flotation, cyanidation) to extract gold from gold-bearing rocks. The selection of the gold extraction process is mainly based on the nature of the ore and the requirements for the product form. The gold extraction process is proposed according to the ore selectability test. There

To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel-like material then enters rotating drums filled with steel balls. In these drums, the ore is ground to a fine slurry or powder.

The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis
