Gold extraction - Wikipedia

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…How Is Gold Extracted From Gold Ore? | Sciencing,Most gold ore now comes from either open pit or underground mines.
