Flotation - 911 Metallurgist

Jan 11, 2016  The FLOTATION PROCESS is one of the commonest methods of extracting the valuable minerals from certain classes of ores, and it is generally more efficient as regards the recovery of the minerals than any other process applicable to the treatment of similar types of ores. The metallic contents of the minerals are recovered from the concentrates in a subsequent series of metallurgical operations ...

Froth Flotation and Gold Extraction - Manhattan Gold Silver

Jul 23, 2014  Most methods of water-based gold extraction are dependent on gold’s lack of buoyancy to work. However, froth flotation uses a different property of gold to separate it from ore. Froth flotation is a method for separating hydrophobic materials (which will not mix with water) from hydrophilic materials (which readily mix with water).

What is the role of depressant in froth floatation process?

Feb 19, 2019  In the froth floatation process, the role of the depressants is to separate two sulphide ores by selectively preventing one ore from forming froth. For example, to separate two sulphide ores (ZnS and Pbs), NaCN is used as a depressant which selectively allows PbS to come with froth, but prevents ZnS from coming to froth.

Settling and flotation have been used for thousands of years to separate particles of dense metals such as gold, using the technique known as panning, in which a sample of gravel or sand is swirled in water in a shallow metal pan.Because the density of gold (19.3 g/cm 3) is so much greater than that of most silicate minerals (about 2.5 g/cm 3), silicate particles settle more slowly and can be ...
