Abstract
A method of beneficiating ore containing barite by a froth flotation process. C.sub.8-34 alpha olefin sulfonates and salts thereof are the active component in compositions which are effective barite collectors and frothers. Additionally, the alpha olefin sulfonates can be admixed with C.sub.8-34 alkyl sulfates, salts thereof, tall oil fatty acids, salts thereof, mahogany petroleum sulfonates, salts thereof, sulfosuccinamates, salts thereof, as well as with admixtures of these compounds to achieve compositions which are efficient barite collectors and frothers.
