Scheelite Flotation Collector In Uzbekistan

2018 3 19 scheelite flotation The collector was a sodium soap of fatty acids formulated from oxidised paraffin (731) which is an industrial grade product and is widely applied in scheelite flotation Sodium carbonate and hydrochloric acid (Tian heng Chemicals) were used to adjust the pH of the pulp

A Highly Selective Reagent Scheme For Scheelite Flotation

Previous studies have proved that the lead complexes of benzohydroxamic acid (Pb ndash BHA) are effective collectors of scheelite flotations however the separation of scheelite from calcite needs depressants with high selectivity In this study we reported a novel depressant for calcite minerals and Pb ndash BHA served as the collector of scheelite The flotation behavior of polyaspartic
