Gold Flotation - 911 Metallurgist

13-07-2016  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.

Froth Flotation and Gold Extraction - Manhattan Gold

23-07-2014  First, refractory gold ore is ground as finely as possible – usually so the individual grains are much less that 100 micrometers. The ground up ore is mixed with water to create a slurry, which is mixed with surfactants to increase the gold’s hydrophobicity. This mixture is placed into a tank or flotation cell filled with distilled water.

01-01-2016  The depression of pyrite at high pH values can be overcome by the addition of more collector, stronger collector, and copper sulfate. Pyrrhotite floats best in acid circuits. The pH range for flotation for gold sulfide ores containing pyrite and arsenopyrite is generally between 7 and 9.

06-02-2018  However, one of the most interesting methods is froth flotation. Froth flotation works by exploiting the hydrophobic properties of gold molecules. First, ore is ground into an extremely fine powder. The powdered ore is mixed with water to create a slurry, which is mixed with surfactants to increase the gold’s hydrophobicity.

Sulphide Flotation - an overview ScienceDirect Topics

Column flotation cells are used in roughing and cleaning duties on a number of mines treating gold ores (Lane and Dunne, 1987). A column cell typically provides higher concentrate grades compared to a mechanically agitated cell; however, losses of coarse gold may be higher in the column cell ( Chryssoulis et al., 2003b ).
