Gold Flotation - Mineral Processing Metallurgy

Jul 13, 2016  Finely divided metallic gold in milling ores floats readily, and a high-grade concentrate can be made by flotation if no interfering slime or gangue is present. Any good collector may be used for the flotation of gold, but organic collectors of the xanthate type produce a cleaner, higher grade concentrate than coal tar-cresote oils.

Improve the separation environment. The flotation method is a widely used technique for the recovery of gold from gold-containing copper ores, base metal ores, copper-nickel ores, platinum group ores and many other ores where other processes are not applicable.

Day 57 Gold Mining, Metallurgy and Prospecting II Rio Suerte

Consequently, gold flotation recovery requires a focus on floating the associated base metals (predominantly lead, copper) and often pyrite minerals. While lime is often used in base sulphide mineral flotation, because excess lime also tends to depress gold flotation, a balance must be maintained between good base metal metallurgy and gold recoveries.

Refractory Gold SGS

This is usually done by flotation of arsenopyrite, pyrite, or other gold-bearing sulfides. To be economically justifiable, preconcentration should meet two objectives. First, the gold recovery to the concentrate should be sufficiently high that the tailings can be discarded without further treatment, and the mass ratio of concentrate to tailings should be low.
