Gold placer mining consists of three major operational steps: extraction, beneficiation and processing. Extraction is defined as removing ore material from a deposit and encompasses all activities prior to beneficiation. Beneficiation is the operation by which gold particles are separated from the associated undesirable material.

Common beneficiation methods include flotation, gravity separation, and gravity separation. ...
Use of NaHS and silver ions has been reported to improve gold recovery at the Los Pelambres mine in Chile (Chryssoulis 2001 ). Sulfide ions appear to act as flotation activators at low concentrations less than 10 −5 M, whereas at concentration above 10 −5 M, it acts as a depressant (Aksoy and Yarar 1989 ).
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 gravity-hydraulic processes weaken, and surface forces become increasingly important (Allan and Woodcock, 2001).These surface forces cause selective attachment through electrostatic, …
