how to make a floatation of gold from ore system

a review of the flotation of native gold and electrum

2001-9-1 · They dry ground a gold ore containing native gold, pyrite, and pyrrhotite and then floated the ground product with copper sulphate, either potassium amyl xanthate or a trithiocarbonate, and a polypropylene glycol frother. They assessed the results by measuring the cyanidesoluble gold (which they called `free gold') in the products

gold extraction - an overview | sciencedirect topics

Dai et al. (2013) found for three concentrate samples studied that the copper dissolution using the copper–ammonia–thiosulfate system was significantly lower than for cyanide, while gold and silver recovery and reagent consumption were dependent on the ore mineralogy (Table 43.11). Despite the lower gold recovery for the flotation concentrate, the copper dissolution and reagent consumption are both much lower for the thiosulfate system

advantages of using gravity concentration for gold recovery

Stop limiting the amount of gold you could be recovering and speed it up! Gravity concentrators produce gold from ore in a matter of minutes or hours rather than days or weeks. By introducing concentrators into your circuit, you can experience faster recovery times, allowing you to produce gold more quickly, which in turn improves your cash flow
