Gold extraction Wikipedia

Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of

Selective attachment processes in ancient gold ore

Various properties of gold can be utilized for beneficiation depending on the particle size. At particle sizes below 100 μm, the mass forces utilized in the gravityhydraulic processes weaken, and surface forces become increasingly important (Allan and Woodcock, 2001).These surface forces cause selective attachment through electrostatic, hydrophobic, or adsorptive effects, which are described
