Jun 15, 2019· The efficient separation of chalcopyrite from arsenicbearing minerals, especially arsenopyrite, remains a challenge in practice. In this work, a novel reagent of NButoxycarbonylOIsobutyl Thiocarbamate (NBOIT) was employed in both single and mixed binary mineral flotation, and it proved to be highly effective for the flotation separation.
Since the inception of the feldspar flotation process using hydrofluoric acid by O’Meara the process has achieved a great commercial success. In the conventional flotation separation of feldsparquartz, hydrofluoric acid is used to suppress quartz and activate feldspar, and a long chain amine salt (acetate or chloride) is used as a collector.
The investigation on calcitephosphate separation was in three main areas: first, a high pH amine float, with various calcite depressants, second, oleic acid float with phosphate ion as a phosphate depressor and, thirdly, flotation of calcite with shortchain saturated acids,
Journal Article: Investigation of thermal treatment on selective separation of post consumer plastics prior to froth flotation
The focus of this investigation was the determination of air flotation parameters to perform solid liquid separation treatment in an activated sludge treating grease waste by promoting filamentous bacteria. The treatment was intended to achieve a pretreatment level, previous to the application of the typical activated sludge process.
The first flotation separation for the rejection of magnesite was reported by Doerner and Dwigh (1930s) .Flotation of Mg carbonates is typically carried out by using fatty acids, since these collectors give insoluble complexes with all divalent cations .Determination of the appropriate depressing reagents for sinking valuable minerals in the presence of collectors for carbonates is a ...
