2014111 · The Telfer processing plant receives ore from three sources, one underground mine and two open pits. Across the ore sources, pyrite content of the ore varies significantly, gold presents as free gold and as discrete grains locked in copper sulphides and pyrite, and copper deportment varies from mainly chalcocite in the open pit ore to …

2019213 · Flotation is also the best method for recovery of gold from base metal ores and gold-containing PGM ores. Excluding gravity preconcentration, flotation remains the most cost-effective bene ficiation method. Gold itself is a rare metal and the average grades for low-grade deposits vary between 3 and 6 ppm.

201451 · 1. Introduction. In porphyry/skarn copper–gold flotation plants gold recovery is often well below copper recovery [1].With liberated and copper-associated gold readily recovered in the flotation stage, this recovery difference is often due in part to operating strategies that require rejection of gold-bearing iron sulphide gangue minerals in order to …

5 · Understanding the Basics of Flotation in Gold Processing. Flotation harnesses the principle of hydrophobicity – where certain mineral surfaces repel water – to separate valuable gold from waste rock. Bubbles are introduced into a pulp of finely ground ore and water, and as the hydrophobic particles attach to the bubbles, they rise to the ...
