Recover Ultrafine Chalcopyrite by Flotation

Apr 03, 2018  Flotation of ultrafine chalcopyrite can be improved by processing the ore with (1) split-circuit design and (2) intense agitation conditioning before flotation. At equivalent or even lower collector consumption, a split circuit flotation design, treating the plus 38- and minus 38-µm-size ore individually, recovered 93 pct of the copper in a 28 ...

A Review on Novel Techniques for Chalcopyrite Ore Processing

Jan 01, 2012  Valuable mineral in an ore such as chalcopyrite ore can be separated from each other and from worthless gauge minerals by the froth flotation process. The process was developed in Australia at the start of the 20 th Century to treat the primary sulfidic silver/lead/zinc ore at Broken Hill (Woods and Doyle, 2000).

Flotation of Puerto Rico chalcopyrite

Flotation is a well known process used in the mining industry for upgrading of low grade ores. The basic dif­ ference in the use of this process depends on the particular type of ore to be treated for extraction. The type of ore determines the grinding operation, the conditioning reagents to be used, the number of flotation cells step, and finally
