Molybdenite flotation from copper/molybdenum

Typically, rougher molybdenite flotation and recovery from bulk copper/molybdenum concentrates involves the use of alkalisulfides, Nokes reagents, cyanides, oxidants, and/or thermal treatment to depress copper sulfide minerals. The bulk copper/molybdenum feed generally varies from 0.2 Mo to 1.0 Mo, and with traditional reagents the single stage rougher flotation recovery of molybdenite

pH Control in Copper Flotation for Maximized Product

Copper ore may be separated from crude ore using a flotation pro­cess that takes advantage of the physical as opposed to chemical properties of small copper ore particles. To maximize the copper yield, pH control is necessary in the flotation tanks. A typical copper operation contains many flotation cells, often with a pH sensor in each cell.

Choosing mineral flotation collectors from large

For the 5 mM conditions in our flotation studies, many of the nanoparticles in our library gave reasonable flotation recoveries. However, there would be problems at higher ionic strength.
