Reagentes depressores de carbonatos: uma revisão

摘要: The presence of carbonates is frequent in phosphate deposits. Several methods have been proposed to remove from ores, but froth flotation the most promising one. Achieving selectivity between phosphates and hampered by similarity physical chemical properties, but use selective depressants may facilitate processing ores with high contents carbonates. This paper presents an overview main reagents used as carbonate possible mechanisms involved adsorption these onto minerals are outlined.
