SEPARATION OF MINERALS

Minerals in low concentration are separated from an ore body by treating the mineral to give it a lyophilic surface, grinding and forming a slurry and then carrying out an agglomeration treatment with addition of an oil and agglomerates of the mineral having a size below 500 microns. The agglomerati...

Beschreibung
Zusammenfassung:	Minerals in low concentration are separated from an ore body by treating the mineral to give it a lyophilic surface, grinding and forming a slurry and then carrying out an agglomeration treatment with addition of an oil and agglomerates of the mineral having a size below 500 microns. The agglomeration treatment is continued with recycling of the agglomerates to increase the mineral content in the agglomerates. Suitable minerals are cassiterite, chalcopyrite, sphalerite and galena.
