The floatability of pyrite is similar to galena under low pH condition, which is harmful to the separation of Pb, Zn and S minerals. The galena will be depressed as well as pyrite if the pH is too high...J. Cent. South Univ. (2012) 19: 2307-2315 DOI: 10.1007/s11771-012-1276-y Separation of sulfide lead-zinc-silver ore under low alkalinity condition SUN Wei(孙伟), SU Jian-fang(苏建芳), ZHANG Gang(张刚), HU......
to precipitate CO32– and HCO3– alkaline anions in bauxite residue and the calcium–sodium substitution reaction can promote conversion of chemical bonded alkali into more stable minerals, thereby inhibiting... sufficient calcium and magnesium ions to reduce alkalinity, engineering applications are still required to solve problems such as inputs and cost. In the meantime, brine treatment introduces a large amount......

floatabilities of calcium minerals and the huge difference between scheelite and wolframite have resulted in difficulties during their separation by flotation in Shizhuyuan Mine. In this study, novel... complexes are found to be selective for the separation of scheelite and calcium minerals with little use of depressants and enable the synchronous flotation of scheelite and wolframite.Hence, a novel......

and with permanent negative charges, illite exhibits the lowest floatability among three aluminosilicate minerals, which is confirmed by the flotation results. The ratio of the broken Al-O to Si-O bonds... floatability among three aluminosilicate minerals. 4 Conclusions 1) The floatability of three aluminosilicates is in the order of pyrophyllite>kaolinite>illite. For kaolinite and illite, SAG8, SAG10......
