Gold Recovery from Gold Copper Concentrates using the,
Hargraves Resources operated the gold copper mine, treating 450,000 t/y of ore containing 5.6 g/t gold and 0.4 % copper, and produced about 72,000 oz/y of gold and 1500 t/y copper using a mixture of gravity and flotation. Overall gold recovery was about 90%. The gravity circuit recovered about 50% of gold in feed and comprised one 30 inch Knelson
5 Types Of Gold Flotation Reagent - Mining-pedia
05-03-2021· Gold flotation reagents can be divided into 5 types: collectors, foaming agents, inhibitors, activators, and pH regulators. Flotation reagent is one of the key factors affecting the flotation of gold ore. It can adjust the surface properties of gold ore during the flotation process, and improve the flotation speed and selectivity.

A review of the flotation of native gold and electrum,
Abstract Native gold and electrum are naturally-occurring alloys containing gold and silver and a little copper. They are the most common and important forms of gold in ores. Their recovery by gravity concentration, cyanidation, or flotation from ores, typically containing 0.1–20 g/t Au is of great commercial importance. This paper reviews the literature on their recovery by flotation.
