Flotation Froth an overview ScienceDirect Topics

The froth flotation technique was originally developed in about 1910 to raise the copper concentrations of the strip-mined ores of Bingham Canyon, near Salt Lake City [9], and was further perfected for the differential separation of lead, zinc, and iron sulfides at Trail, B.C., at about the same time [10]. Flotation technologies are now widely

This flotation step is conducted at alkaline pH. In the case where galena is floated and the copper minerals are depressed, copper depression can be achieved by using sodium sulphide, hydrosulfite, lime, cyanide, zinc-cyanide and/or ferricyanide complexes. Selection of flotation reagents and frothers is an important, even critical, consideration.

Talk:Copper extraction Wikipedia

Copper has a density of 89.4 g/cc, so a 100 cm by 100 cm by 1 cm plate of pure copper will weigh 89.4 kilograms. It is therefore unlikely that a 96cm by 96cm by 1cm plate of copper will weigh 100 kilograms, as previously stated in the article. Commodity copper is about a meter square by 1 centimeter thick weighing about 200 lbs.
