Leaching of chalcopyrite (CuFeS2) with an imidazolium ...

2016-12-1  1. Introduction. CuFeS 2 is the most abundant primary copper sulphide mineral and by far the most refractory towards hydrometallurgical processing (Debernardi and Carlesi, 2013).The slow dissolution of this mineral in sulphate media results in an inefficient industrial process. CuFeS 2 dissolution in chloride media results in faster kinetics (Ruiz et al., 2011).

Sulfuric Acid Leaching of Heavy Rare Earth Elements

2020-10-16  Solid pollution has been an issue in mineral processing for decade. One of these pollutants is zircon sand mining waste (zircon tailing). Due to the concentration of rare earth minerals in zircon tailing and the increasing demand of REE in advanced technologies, studying zircon tailing as a potential source of REE had become an interest for us.

2021-11-18  Large minerals only require a coarse grind, whereas small sized minerals require a finer grind. The slurry of crushed rock and water is placed into an agitator tank, a frothing chemical is added and a collecting chemical, usually a xanthate, is also added to the tank. The xanthate attaches itself to the sulfide mineral making it hydrophobic.
