In contrast to modern tailings from froth flotation, little is known about historic tailings from gravity separation. However, they may be of economic interest due to their higher metal grades compared to modern tailings. As an example for these types of historic tailings, the inner structure, as well as the economic potential (Pb, Zn, Cu, Ag, Sb), of the old Bergwerkswohlfahrt mine waste dump ...

An Overview of Calcite Recovery by Flotation | SpringerLink

Sep 23, 2020· Calcite ores typically contain metal sulphide, silicate, or other calcium-containing impurity minerals, which can be removed by flotation. A tremendous amount of research has been performed on refining the flotation process for calcite ores and designing the reagents (specifically, collectors) to increase the efficiency of the process.

Selective Flotation of Scheelite and Calcite - [email protected]

The gold tailings from Gold Fields containing low scheelite values has a compled mineralogy with hornblende, quartz, arsenopyrite and calcite as major gangue minerals. The most difficult problem in scheelite flotation is not the removal of the siliceous or sulphide gangue, but the separation of Scheelite and calcite minerals which have similar surface properties.

Selective flotation of scheelite and calcite

flotation tests to recover scheelite from tailings failed due to the dilution of the concentrate by calcite. Hence to adopt the flotation process successfully, it is necessary to depress the calcite selectively which is not achieved easily(2) due to the presence of small amounts of Ca, Mg and Fe salts and the lean grade of the ores to be treated.
