Fig. 1 shows seven mills …
Even when the recovery of the gold and silver values from such ores by flotation is low, it may still be advantageous to float off the minerals which interfere with cyanidation, roasting and cyaniding, or possibly smelting, the concentrate for the extraction of its precious metal content; this is followed by cyanidation of the flotation tailing ...
However, the flotation performance of pyrite is poor in alkaline seawater, due to the formation and adsorption of seawater precipitates on pyrite surface [19].Therefore, more collectors or activators are normally required [15].Previous studies show that copper ions (Cu 2+) are the common activator during pyrite flotation in fresh water [20], [21], [22], where the Cu/Pb …
The FloatForce and Center Launder upgrades were used to retrofit rougher flotation cells at Glencore Antapaccay Copper Mine in Peru which increased copper recovery, produced revenue growth, provided operational flexibility due to deeper froth beds and decreased airflow rates, reduced energy consumption and lowered operating costs.

The flotation process typically consists of two copper roughing flotation benches, each consisting of seven forced-air mechanical flotation cells. These produce a coarser low-grade concentrate containing copper, silver, gold, molybdenum, and other non-valuable gangue and sulfide minerals (mine tailings) [ 44 ].
Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water …
