Column flotation has an advantage over conventional flotation as it can provide higher concentrate grade and recovery, lower maintenance costs, and improved process control [50]. Flotation variables are the pH of pulp, types and dosages of reagents, percentage of solid in pulp, temperature and agitation rate [51] .

It is believed that a flotation process is primarily the result of the tendency of certain surface-active species to concentrate at the liquid–gas interface and the tendency of some other species or particles to associate with or adsorb these surface-active species [1]. The techniques based on the ability and tendency of various species to ...

The conventional practice for producing copper and molybdenum metal from Cu–Mo sulfide ores is (1) bulk flotation to produce a mixed concentrate of chalcopyrite and molybdenite, (2) depression flotation to obtain a separate concentrate of chalcopyrite and molybdenite, and (3) sending the concentrate to its metallurgical process.

C = F/K = F (f — t) / (c-t) = the weight of the concentrate. Recovery % Represents the ratio of the weight of metal or mineral value recovered in the concentrate to of the same constituent in the heads or feed to the process, expressed as a percentage. It may be calculated in several different ways, depending on the data available.
