US3701421A Method of mineral separation by froth

A method of mineral separation by froth floatation in which pulp is fed into a cylindrical tank of height approximately equal to its diameter. The pulp is mechanically agitated, and air at low pressure is fed into the bottom of the tank, to keep the tank contents in suspension and to float the desired fraction of the pulp. The feature of the invention is that a low flow of air is used, in the ...

Kinetics Of Flotation Concentration Of Minerals

Kinetics of flotation CONCENTRATION OF MINERALS

Flotation kinetics from the Greek Kintik s - driving is studying the regularities of flotation process at the time, the rate and the flotation mechanism. Kinetics of flotation reflects the flotation results in variable states and is characterized by dependency of the recovery R of floatable mineral in concentrate from time t, i.e. R f t. It allows a quantitative description of the flotation process in time.

The final step in mineral separation is by preferential flotation of mineral fractions by heavy liquid. Nonmagnetic fractions first undergo separation by sodium polytungstate SPT 2.85 gcm3 and finally by methylene iodide MEI 3.3 gcm3. At the end of separation, the final fraction should contain minerals such as zircon, apatite, monazite ...

Jun 08, 2016 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.
