May 22, 2016 · A modern high – tonnage copper mill equipped with Free-Flow Flotation Machines. Flotation concentrates are combined from all cells and then further upgraded by cleaning in

A process for separating molybdenite from copper concentrates containing copper and iron sulfides, ... United States Patent 3811569 ... the pH of the pulp is adjusted to provide proper conditions in the rougher flotation cells. Thus, in order that the ferrocyanide function satisfactorily as a depressant, the pH should be between 6.5 and 8.5 and

Injection of steam into the pulp prior to molybdenite flotation alters copper and iron sulfide mineral surfaces so that they are less naturally floatable, decomposes residual flotation reagents that promote copper and iron sulfide flotation, and reduces sulfide reagent consumption by lowering the solubility of dissolved oxygen

There are 1,766 suppliers who sells copper flotation machine on Alibaba.com, mainly located in Asia. The top countries of supplier is United States, from which the percentage of copper flotation machine supply is 1% respectively

Feed slurry was mixed with entrained air in an agitation box (reactor) and flowed into the separation vessel where froth was collected as overflow. The design would be the basis for the Minerals Separation Corporation standard machine and early flotation cells used in the United States (Lynch et al., 2010)

Apr 13, 2016 · Copper Sulfide Flotation Circuit. The pulp from the Conditioner is treated in a 10-cell “Sub-A” Flotation Machine and a 4-cell “Sub-A” Flotation machine. Sometimes conditioners are not provided; however, their use insures that reagents are thoroughly mixed into the pulp ahead of flotation
