In gold winning, activated carbon is used to extract the gold cyanide complex. Coconut shell based activated carbons are excellently suited to this application because of their extreme hardness, excellent adsorption characteristics and good regenerability.
Sodium cyanide is widely used in different field of industry. Especially, it is important for obtaining precious metals: gold, silver and platinum by hydrometallurgy method. A sodium cyanide solution is commonly used to leach gold from ore.
Mercury is used to capture gold particles during the ore processing stages in ASGM through a process called amalgamation. Mercury acts like a magnet to gold and bonds with it, creating an approximately 50-50% alloy of mercury and gold, which permits the gold to separate from the rest of the minerals.
Grinding balls are used in the mining, coal, construction (for example, to make cement) and other industries: in ball mills as grinding bodies for grinding materials by impact, abrasion and crushing. The balls are produced from iron and steel.
