Abstract

Email to a Friend
(NH4)2SO4 can be used with success as a leachant to remove gypsum contained in celestite ores. The process, which is applied before flotation, provides an upgraded feed and problems related to the simultaneous flotation of CaCO3 and SrSO4 are reduced. The process is independent of the gypsum content of the feed so that each leaching stage decreases the gypsum content by almost 50%. The use of (NH4)2SO4 has an insignificant effect on the co-leaching of SrSO4 (0.45 wt.%) at each stage
