Concentration of fluorspar ores in the Illinois-Kentucky
The importance of fluorspar in the industrial development of the country, particularly in the open hearth steel and growing almninum industries, has just begun to be fully realized. During the World War fluorspar was found to be an essential mineral, but it also was found to be one which was not as abundant . in . commercial
Beneficiation of fluorspar ore International Minerals
A method is disclosed for beneficiating a fluorspar concentrate containing apatite as a gangue mineral, which includes further concentrating the fluorspar by a froth flotation process wherein the apatite is collected and floated with a cationic reagent in an acid flotation circuit and the fluorspar is depressed with fluoride ions.
Concentrating fluorspar by froth flotation Nasa
The process of concentrating fluorspar by froth flotation of pulps containing fluorspar values, comprising adding to such a pulp a soluble inorganic fluoride, a lignin sulphonate, and a fluorspar collecting agent selected from the class consisting of fatty acids and soaps, and subjecting said pulp to froth flotation to recover the fluorspar. 3
