In the mining industry, cyanide is primarily used for leaching gold and silver from ores, but it is also used in low concentrations as a flotation reagent for the recovery of base metals such as copper, lead, and zinc. At many of these operations, cyanide treatment systems may be required to address potential toxicity issues in regard to the health of humans, wildlife, waterfowl, or aquatic life.

Phosphate ore is an important raw material for manufacturing fertilizers and phosphorous chemical products. While most of the phosphate resources cannot be directly treated as feed stock due to the low grade of P2O5 and high content of impurities. In order to obtain a qualified phosphate concentrate, the beneficiation of the low-grade phosphate ore is, hence, of great necessity.
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

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.
