Introduction to Gold Extraction
Gold extraction is a complex and multi - stage process that involves the separation of gold from its ores. The process typically begins with mining, where gold - bearing rocks are extracted from the earth. After mining, the ore is crushed and ground into fine particles. Then, various techniques such as cyanidation, gravity separation, flotation, and smelting are employed to isolate the gold. Cyanidation is one of the most widely used methods, which uses a cyanide solution to dissolve the gold from the ore. Gravity separation relies on the difference in density between gold and other minerals, while flotation uses chemicals to make the gold particles attach to air bubbles and rise to the surface. The final step usually involves refining the extracted gold to achieve high purity.
