95.5% of its content in the original concentrate. Specific consumption of sodium cyanide was 51% of the consumption of sodium cyanide in the of from the original concentrate, i.e. with increasing by 30% specific consumption of sodium cyanide was reduced about 2 times.read more
First, the material is screened to remove large rocks and boulders. Then a sluice or jig is used to the For deposits with high clay content, the rocks are cleaned with a trommel or rotary scrubber to remove contaminants, and then can take place. If a significant portion of the is fine <300 μm, a high G-force gravity concentrator like the Falcon SB Concentrator can be used to improve …read more

Problem with from ore: How may a mill get the maximum of from a ore, at the least capital cost and at the same time obtain the highest net return. This latter point is most important. In many cases a mill using an all-cyanide flowsheet with grinding of all the ore will report very low content in the tailings particularly on an ...read more
Generally, recovery of the gold from the sulfide concentrates requires further processing, usually by roasting or wet pressure oxidation. These pyrometallurgical or hydrometallurgical treatments are themselves usually followed by cyanidation and carbon adsorption techniques for …read more
