5 TPH Gold Rock Complete Mineral Process Line Gravity Separator The content of gold in the ore is extremely low. In order to extract the gold, the ore needs to be crushed and ground and the beneficiation method is used to preenrich or separate the gold from the ore. The most widely used in gold beneficiation is gravity separation and flotation.

ABSTRACT Gold and copper thiosulfate adsorption from an alkaline gold ore leachate was investigated by using polyethyleniminecoated iron oxide magnetic nanoparticles (NPs). The ore, sourced from a mine in Nevada, USA, was leached with calcium thiosulfate for 48 h in the presence of Cu(II) at a pH of 8 and a temperature of 50°C. A response surface methodology was used to analyze the effect of
