calculations, and proposed that the precipitation of Ca(OH)+ and Ca(OH)2 on spodumene surface contributed to the activation of spodumene flotation. In alkaline solutions, Ca2+ and Mg2+ ions readily form......
germanium from these effluents, various techniques have been developed [4]. Liquid-liquid extraction (LLX) [6], ion exchange [7], ion flotation [8], adsorption [9], precipitation [10], and emulsion..., WANG J, WANG Y. Germanium recovery by co-precipitation of germanium and iron in conventional zinc metallurgy [J]. Journal of the Southern African Institute of Mining and Metallurgy, 2008, 108: 715-718......
rate through jarosite and S precipitation. Nevertheless, the difference could be attributed to the mineralogical composition of the ore used; the iron and sulphur concentrations in the overall matrix......
adsorption of collector onto chalcopyrite surface. The oxidative treatment can dissolve the mineral surfaces into their respective metal species in the solution and the precipitation of these species......
by ferro-actinolite and magnetite, but in this case calcite is also part of the secondary product. After the initial precipitation of magnetite, it is further altered to pyrite which indicates......
