Gravity Concentration in Artisanal Gold Mining. Many gravity concentration methods used by artisanal miners are discontinuous, i.e., miners stop the process to discharge the concentrate after some time of operation. Some miners have the perception that when they see a yellow concentrate, the gold recovery is good, and the equipment works well.
