Flotation of copper oxide minerals: A review
Abstract. Copper oxide minerals are important copper resources, which include malachite, azurite, chrysocolla, cuprite, etc. Flotation is the most widely used method for the enrichment of copper oxide minerals in the mineral processing industry. In this paper, the surface properties of copper oxide minerals and their effects on the …

Research On Copper-molybdenum Ore Flotation Separation Process
The process is to float molybdenum first, then grind to separate copper and molybdenum, and flotation molybdenum tailings to recover copper. 3. Equal flotation Process. Generally speaking, both preferential flotation and mixed flotation require high alkalinity (lime) to achieve separation of copper, molybdenum and sulfur.

Development of copper recovery process from flotation …
The total copper recovered from its ore through flotation process is about 56% [6, 18], which indicates that the flotation tailings still contain valuable copper components such as chalcopyrite. In addition, old flotation tailings sometimes have a higher copper grade (0.2–0.4%) than that of low‒grade ores (0.2‒0.3%).

Current Status of Copper-Ore Processing: A Review
The bulk flotation and the sulfide flotation of copper from atmospheric leaching cake in the future copper ore processing plant at the Udokan deposit is planned to be carried out at pH 9.0–10.5 and 5–6, respectively. Lime milk will be used to form and maintain the pH medium. One problem in the flotation process is the presence of sludges.
