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(More rare than diamonds), as fine grains or flakes in alluvial deposits , or as grains or microscopic particles embedded in other rocks. Ores in which gold occurs in chemical composition with other elements are comparatively rare. They include calaverite , sylvanite , nagyagite , petzite and krennerite . A "refractory" Gold ore is an ore that is naturally resistant to recovery by standard cyanidation and carbon adsorption processes. These refractory ores require pre-treatment in order for cyanidation to be effective in recovery of the gold. A refractory ore generally contains sulfide minerals , organic carbon, or both. Sulfide minerals often trap or occlude gold particles , making it difficult for the leach solution to complex with the gold. read more
