Gold Flotation - Mineral Processing & Metallurgy
GOLD FLOTATION. The flotation process, which is today so extensively used for the concentration of base-metal sulphide ores and is finding increased use in many other fields. In 1932 flotation plants began to be installed for the treatment of gold and silver ores as a …
Fine Gold Recovery by Flotation
Although gold readily and naturally forms a hydrophobic film, dithiophosphates have been advanced as more selective for gold than xanthates and float gold up to 200 micron in size despite its density. Our initial investigations in the mechanical flotation cell were with a wide variety of samples, including beach sands and alluvium.

Froth Flotation and Gold Extraction - MGS Precious Metals Blog
Jul 23, 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.

What is the gold froth flotation process? - Quora
The ore often contains about 2% or less of pyrite. In order to do a better stone of recovering the gold from the pyrite you may want to separate as much of the pyrite from the rock as possible. A flotation cell, or set of cells, can produce a concentrate that is around 50% to 80% pyrite.
