Handbook of flotation reagents. Volume 2. Chtmistry, theory and practice; Flotation of gold, PGM and oxide minerals / Руководство по флотации. Часть 2. Химия, теория и практика; Флотация золота, МПГ и оксидов

Volume 2 of the ‘Flotation Reagents Handbook’ is a continuation of Volume 1, and presents fundamental and practical knowledge on flotation of gold, platinum group minerals and the major oxide minerals, as well as rare earths.

Rather than reiterating what is well known about flotation of gold, PGMs and oxide minerals, emphasis has been placed on the separation methods which are not so effective when using conventional treatment processes. These difficult separation methods are largely attributed to problems with selectivity between valuable minerals and gangue minerals, especially in the flotation of oxide ores and base metal oxides, such as copper, lead and zinc oxide ores.

Literature on flotation of gold, PGMs, rare earths and various oxides is rather limited, compared to literature on treatment of sulphide-bearing ores. As mentioned earlier, the main problem arises from the presence of gangue minerals in the ore, which have flotation properties similar to those of valuable minerals. These minerals have a greater floatability than that of pyrochlore or columbite. In the beneficiation of oxide minerals, finding a selectivity solution is a major task. <...>
