Flotation is widely used to concentrate copper, lead, zinc, iron and even gold and silver minerals, which commonly accompany one another in their ores. Many complex ores formerly of little value have become major sources of certain metals by means of the flotation process.

Copper Mining and Processing Processing of Copper Ores

The froth of copperrich bubbles at the top of the tank is then skimmed off for further processing. The gangue sinks to the bottom of the tank to be removed or disposed of as mine tailings. The next stage after froth flotation is the thickening stage. The froth is poured into large tanks called thickeners.

A review of the flotation of native gold and electrum

Native gold and electrum are naturallyoccurring alloys containing gold and silver and a little copper. They are the most common and important forms of gold in ores. Their recovery by gravity concentration, cyanidation, or flotation from ores, typically containing 0.120 g/t Au is of great commercial importance.

Flotation Froth an overview ScienceDirect Topics

Flotation of Gold and GoldBearing Ores. The indispensable tool for Cu concentrate production is froth flotation (Fuerstenau, Jameson, amp; Yoon, 2007). This technique is used to upgrade an ore to a concentrate by selectively floating coppercontaining minerals away from noncopper minerals. The principles of froth flotation are as follows

Froth Flotation Principles

The Froth Flotation Machine and its operating principles are universally used for all types of flotation problems.This machine finds a wide acceptance due to its flexibility in construction, which allows the machine to be adjusted to handle pulps with divergent physical characteristics, as well as the common and intricate metallurgical problems which confront the present day operator.

Gold extraction

Froth flotation is usually applied when the gold present in an ore is closely associated with sulfide minerals such as pyrite, chalcopyrite or arsenopyrite, and when such sulfides are present in large quantities in the ore. In this case, concentration of the sulfides results in concentration of gold values.
