Flotation Archives Flotation responses of these minerals in the presence of potassium oleate and sodium silicate are presented and compared with electrokinetic data Colloidal silica appears to be the species principally responsible for calcite depression, while silicate anion is the species responsible for fluorite depression Additions as high as 1 x 10-³ mole ....
PROCESS FOR THE FLOTATION OF FLUORITE Nov 30, 1971· More particularly, we have found new reactants which, used together with those previously employed for the flotation of fluorite, provide a simple and inexpensive solution to the problem In accordance with the present invention, an ethoxylated alkyl phenol and an ethoxylated fatty acid are employed to condition the ore prior to flotation...
Flotation Process For Fluorspar Jun 11, 2017 Fluorite and Fluorspar: Mineral uses and properties Fluorite has physical properties that allow it to That company is developing an underground mine to exploit a large vein of fluorite which they hope will be in Fluorite Flotation SeparationOre Beneficiation,Flotation 3The preparation method of fluorite flotation agent A process...
Flotation Reagents Flotation Frothers What is the Function of Frothers The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the non-floatable minerals Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form...
