Beneficiation Methods for Different Gold Ores and

2020-7-27  Gold beneficiation jigger. Gold floatation separation. Floatation separation is one of the most common beneficiation methods for quartz gold ore. Mostly, floatation separation makes a high beneficiation efficiency over the sulfide ore of gold with its high flotability. By floatation, both gold and other metals can be separated, and the tailings can be of no value.
