Only the flotation process mentioned above could make this practicable; and even so, it requires large companies with huge plants, continuous working and immense capital. This explains why, in order to smelt 4 million tons of new copper in 1963, nearly 400 million tons of ore had to be handled and treated in various ways.

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 non-floatable 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 surface in bubble form.

In this paper, we examine these questions. A new compartmental model of flotation is proposed, one that is effective for both single- and dual-chamber machines. An example model calibration is provided, from test work performed at Capstone's Pinto Valley concentrator, showing that the new approach works well for dual-chamber flotation cells.

The costs of froth flotation are aggregated in this data-file, building up the typical capex costs (in $/Tpa), energy costs (in kWh/ton) and other opex lines (in $/ton) of one of the most important processes for the modern metals and materials industry. A good rule of thumb is $10/ton costs to concentrate ore by over 4x (this excludes underlying ore costs).

A survey of plant operations (O'Connor and Dunne, 1991) revealed that many flotation operators observe that copper sulfate addition appears to influence mainly the froth stability and that there is an optimum dosage – too little resulting in high slime recoveries and too much resulting in froth instability (O'Connor et al., 1990).

Conditions of operation of froth-flotation. Froth-flotation is in general effective only on ores ground to pass 0.3-mm. aperture or less and the agitation-froth and bubble-column processes are most effectively practiced when the bulk of the feed will pass a 0.074-mm. screen.
