froth floatation method

How to Extract Precious Metals From Sulfides Sciencing

The most popular method of separation is the froth floatation method, which was specifically designed for sulfides as opposed to smelting which is more suitable for larger veins of metal ore. Another more modern method uses microorganisms to separate the metals from the sulfur.

Froth flotation WikiMili, The Free Encyclopedia

For froth flotation, the ground ore is mixed with water to form a slurry and the desired mineral is rendered hydrophobic by the addition of a surfactant or collector chemical (although some mineral surfaces are naturally hydrophobic, [21] requiring little or no addition of collector). The particular chemical depends on the nature of the mineral to be recovered and, perhaps, the natures of those that are not wanted.
