Anionic flotation of high-iron phosphate ores—Control of
网页2009年7月1日The anionic flotation of phosphate ores generally relies on the use of fatty acid surfactant-type collectors. The selectivity of the process results from a high chemical affinity of the anionic surfactants towards these sparingly-soluble salt-type minerals (Peck and Wadsworth, 1963, Peck and Wadsworth, 1965).
