Gold Flotation Process means that gold ore is generally crushed by gold mining equipment , then crushed by gold processing equipment , and then treated by gold panning equipment such as flotation machine, etc. Through gravity separation, flotation machine, extraction of metals from ores, and then the ...
Where a high sulphide recovery is demanded, flotation methods are now in general use, but in the days before flotation was known, a large part of the worlds gold was recovered by concentrating the gold bearing sulphides on tables and smelting or regrinding and amalgamating the product. Though the modern trend is away from the use of tables, because flotation is so much more efficient.
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 golds hydrophobicity.
The ground up ore is mixed with water to create a slurry, which is mixed with surfactants to increase the golds hydrophobicity. This mixture is placed into a tank or flotation cell filled with distilled water. Air bubbles are pumped into the flotation cell and the water is agitated.
