Flotation of Gold Ores. Srdjan M. Bulatovic, in Handbook of Flotation Reagents: Chemistry, Theory and Practice, 2010 Publisher Summary. In spite of the lack of basic research on flotation of gold-bearing ores, the flotation technique is used not only for upgrading of low-grade gold ore for further treatment, but also for beneficiation and separation of difficult-to-treat gold ores.

Each class of skarn deposit has a characteristic, though not necessarily unique, size, grade, tectonic ...
Compared with magnetic roasting-magnetic separation, deep reduction-magnetic separation is a more suitable method for enriching the iron from Zn- and Pb-bearing refractory iron ore, given the contents of Fe, Pb and Zn in the concentrate. The obtained concentrate with >90% Fe can be directly used in the steel production process.
Iron oxide-copper-gold (IOCG) deposits, defined primarily by their elevated magnetite and/or hematite contents, constitute a broad, ill-defined clan related to a variety of tectono-magmatic settings. ...

On the basis of a sound evaluation of literature's data, the Co/Ni ratio in pyrite proves a more reliable indicator in ore genesis than previously retained. This is particularly true for volcanogenic pyritic ores which are constantly characterized by Co/Ni values (>5 but more often >10) definitely higher than those attained by sedimentary or hydrothermal pyrites. Moreover, once stated that …
