INTRODUCTION Flotation is the separation of particles from a mixture by causing some particles to collect on the surface of bubbles. Floatation is an extractive process where various minerals can be selectively extracted. For example, in poly-metal ores such as Pb-Zn-Cu, floatation allows separate extraction of Pb, Cu and Zn. The process of ...
the flotation separation of molybdenite and talc, and the adsorption characteristics of HA on these two hydrophobic minerals have been investigated through equilibrium adsorption studies, diffuse
Disadvantages of Flotation | Shares. In this article we will discuss about the disadvantages and drawbacks of flotation. (a) There are considerable costs in flotation and listing. (b) It takes lot of management's time, before and after flotation and listing. (c) The company must comply with the stringent stock exchange regulations.
where Coo is the concentration of the mineral in the flotation cell, even after a long flotation time. The flotation rate equation is used to predict flotation recovery, grade of concentrate, and separation efficiency as functions of flotation time. The predicted values of these quantities are in agreement with the experimental values.
Zhu (2011) studied the effect of surface dissolution on the flotation separation of fine ilmenite from titanaugite and found that in an acid solution, Ti (IV) and Fe (III) are the major activated sites for the adsorption of NaOL onto the ilmenite surface; the effect of Ca (II) and Mg (II) is very weak.
