Gold recovery cyanide process is widely used. A professional gold recovery industry that handles high-sulfur, high-arsenic, and other refactory gold concentrates, the arsenic grade is about 10%. The high-sulfur and high-arsenic gold concentrate is pretreated by two-stage roasting, and the two-stage roasting sand is leached into the gold recovery cyanide process by sulfuric acid leaching.
The cyanidation gold extraction process is the main method for extracting gold from ores or concentrates. Percolation cyanidation process is a method of gold cyanidation processes. Percolation cyanidation method is a relatively simple and inexpensive method of extracting gold.
