Pyrite Tailings Recovery By Flotation

May 07, 2016 Pyrite has long been used as a source of sulphur, and its recovery as a by-product from the flotation of certain base metal ores is a well established practice.

Taking the barite quartz calcite type ore separation as an example, in the flotation gravity separation combined process, by adding sodium silicate and collector to the flotation cell to remove quartz impurities, the barite and calcite mixed ore is obtained, and then.

Flotation Of Fine Size Barite From Gravity Separation Tailings

May 01, 1995 The concentration of barite by gravity separation generates substantial quantities of fine-particle wastes, and it is estimated that ≈40 of the contained barite is lost to these waste streams. In this study, froth flotation was examined as a potential method for the recovery of fine-barite particles. The study included the use of kinetic equations to estimate the variables effecting.
