Lime in Base-Metal Flotation

THE most useful guide to the role of lime in flotation is the view that the chemistry of any flotation operation is primarily a pattern in relative solubilities. We have the coming together of a number of minerals, reagents, fortuitous salts, water, and oxygen, many of which have not been previously in contact with each other, and every one of which is free, at least to some extent, to abandon old alliances and to form new ones . Of one thing the operator may be sure, and that is that, when equilibrium has been reached, those new chemical combinations will have formed which are the least soluble combinations possible to the environment.
