Solvent extraction of Cu, Mo, V, and U from leach

2017-8-3  Flotation tailings from copper production are deposits of copper and other valuable metals, such as Mo, V and U. New hydrometallurgical technologies are more economical and open up new possibilities for metal recovery. This work presents results of the study on the extraction of copper by mixed extractant consisting p-toluidine dissolved in toluene.

Techniques of copper recovery from Mexican copper

2009-1-1  Mexican copper ore is a mixed ore containing mainly copper oxide and some copper sulfide that responds well to flotation. The joint techniques of flotation and leaching were studied. The results indicate that an ore containing 19.01% copper could be obtained at a recovery ratio of 35.02% by using sodium sulfide and butyl xanthate flotation.

US4874534A Method for removal of organic

An improved method of separating organic solvents from aqueous process streams is disclosed in connection with a copper solvent extraction/electrowinning process. An aqueous solution having droplets of an organic solvent entrained therein is admitted to the upper part of a vertically extending vessel, and air bubbles are passed therethrough from an air inlet near the bottom of the vessel.
