MacArthur-Forrest Process
The MacArthur-Forrest process is a method used to extract gold from ore using cyanide, a chemical that binds to gold particles. The ore is crushed and mixed with a cyanide solution, which dissolves the gold. The gold-laden liquid is then separated and treated with zinc, causing the gold to settle out of the solution. This process is efficient for recovering gold from low-grade ore but requires careful handling of toxic chemicals to ensure environmental and safety standards are maintained. It revolutionized gold mining, making extraction more economical and feasible on a large scale.
