This invention relates to a liquid composition, comprising: greatr than about 65 % by weight of an alkali or alkaline earth metal salt of a thiophosphorus acid having hydrocarbyl groups each independently containing from about 2 to about 8 carbon atoms; and at least about 1 % by weight water. In another aspect, the invention relates to an oil-free liquid composition, comprising: greater than about 65 % by weight of an alkali metal salt of a thiophosphorus acid having hydrocarbyl groups each independently containing from 2 to about 8 carbon atoms, and water. The liquid compositions have low water content. These compositions are easy to handle and have reduced transportation costs. These materials are liquid and are especially useful as ore flotation agents. |
