Copper Flotation Ground Micron Mesh Porphry

Copper Flotation

Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper operations must be relatively large in order to be commercial. The flowsheet in this study illustrates a typical 3,000 ton per day operation. In general most operations of this type have two …

Coarse PartiCle Flotation

of Coarse Flotation The ability to float coarse particles minimizes grinding requirements as only a small fraction of the feed is ground to the traditional liberation size – reducing energy consumption or increasing mill capacity. With maximum production of coarse reject material, the ability to manage tailings is vastly improved.

Column Flotation of Copper

A column flotation system was designed to conduct release analyses of a very finely disseminated, stratiform, copper ore from the Denali Copper Prospect, Alaska. Chalcopyrite is finely disseminated in a carbonate matrix and pyrite is disseminated in both the chalcopyrite and gangue, requiring grinding to 20 microns for adequate liberation.
