Description

TECHNICAL FIELD

[0002] Cyanide leaching is a mineral leaching process using a solution containing cyanide as a leaching agent to extract gold and silver from gold and silver-containing mineral raw materials. The cyanide leaching process mainly includes heap leaching process and tank leaching process. The tank leaching process mainly includes raw ore cyanide leaching process and concentrate cyanide leaching process. Different leaching raw ore properties and processes will produce different pollutant concentrations of cyanide-containing tailings slurry.
