Gold Leaching Flowsheet C1. This flowsheet is for a medium grade ore where a high recovery is made by the Mineral Jig in the grinding circuit and where a large percentage of the fine gold is dissolved during grinding. The solution is then sufficiently high grade to warrant removal by the primary thickener and sending to precipitation.


Concentration of gold flotation ProcessFlotation for large density and coarse particle needs thick pulp whereas for small density and fine particle need dilute pulp. Other Process conditionsIn addition to the grinding fineness Process conditions of gold flotation also includes slurry concentration reagent dosage aeration quantity flotation time.
