froth flotation stage guiana. Flotation Frothers What is the Function of Frothers The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the nonfloatable minerals Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the ...

The ore is processed by froth flotation comprising rougher and scavenger cells. The common reagents for copper ore flotation are xanthates as collector, pine oil as frother, sodium cyanide as depressant, and lime to maintain slurry alkalinity. The concentrate in the form of froth and slurry contains +20% copper. It is thickened in a rake-type unit from a level of 30% solid content to 60%. The ...

Ore - Wikipedia
Ore is natural rock or sediment that contains one or more valuable minerals, typically metals, that can be mined, treated and sold at a profit.Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals.. The grade of ore refers to the concentration of the desired material it contains.

Mineral Processing - an overview | ScienceDirect .
Froth flotation is a long established technique in mineral processing. Extensive discussion of flotation can be found in the book by Leja (1982); see also recent work by Fecko et al. (2005) and Melo and Laskowski (2006). Basically, particles are either hydrophilic or hydrophobic (Gutierrez-Rodriguez et al., 1984). Surface properties of particles are modified with a surfactant (collector ...

Graphite - Geology
When graphite is in high enough concentrations, these rocks can be mined, crushed to a particle size that liberates the graphite flakes, and processed by specific gravity separation or froth flotation to remove the low-density graphite. The product produced is known as "flake graphite."
