  • Recover Ultrafine Chalcopyrite by Flotation

    Hydrophobic Nature of Ultrafine Chalcopyrite. The ultrafine chalcopyrite from the nearly pure chalcopyrite specimen showed significant natural hydrophobicity as shown in figure 4. With no KAX, over three-quarters of the chalcopyrite floated. Virtually all of the 20- by 10-µm chalcopyrite was recovered in the flotation concentrate.

  • A Review on Novel Techniques for Chalcopyrite Ore Processing

    Chalcopyrite ores are usually processed by means of hydrometallurgical or pyrometallurgical processes, but due to environmental aspects and the possibility of increased exploitation of mixed and lower grade ores and relatively small isolated deposits, there has been a worldwide upsurge of interest in the hydrometallurgical processes of this ore as compared to pyrometallurgy.
