Figure 5 presents the flotation flow sheet developed a previous desliming stage is crucial for slimes removal followed by three flotation stages starting with a rougher stage The rougher concentrate RC was upgraded in a cleaning stage that produced a final clean concentrate CC and a middling product with highlithium content CT
Fine and ultrafine feed is easily processed using column flotation and returns recoveries exceeding 90 Depending on the application ie rougher or cleaner the products can either be of final grade or tailored for the various downstream processes such as amine flotation depending on
Flotation Froth An Overview Sciencedirect Topics Copper ore usually contains about 05 to 2 copper that occurs in the form of disseminated and stringers the run of mine ore is reduced from 150 mm to 25 mm size in jaw and cone crushers the crushed ore is grinded in ball mills to 74 m size the ore is processed by froth flotation comprising rougher and scavenger cells
Flotation of Chromite Ore Petrographic examination of the pH 20 flotation products showed olivine to be present in the concentrate while serpentine remained in the tailings To increase the selectivity of Mouat ore to amine flotation of chromite a selective olivine depressant must be found
