How Is Gold Extracted From Gold Ore? Sciencing

The zinc causes a chemical reaction which separates the gold from the ore. The gold is then removed from the solution with a filter press. For the carbon-in-pulp method, the ground ore is mixed with water before cyanide is added. Then carbon is added to bond with the gold. The carbon-gold particles are put into a caustic carbon solution, separating out the gold. In heap-leaching, the ore

Gold extraction

Gold occurs principally as a native metal, usually alloyed to a greater or lesser extent with silver (as electrum), or sometimes with mercury (as an amalgam). Native gold can occur as sizeable nuggets, as fine grains or flakes in alluvial deposits, or as grains or microscopic particles (known as color) embedded in rock minerals. Ores in which gold occurs in chemical composition with other elements are comparatively rare. They in

Extracting Gold HowStuffWorks

To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel-like material then enters rotating drums filled with steel balls. In these drums, the ore is ground to a fine slurry or powder.
