Read MoreFroth flotation is a process for selectively separating hydrophobic materials from hydrophobic. In some cases, for example, sulphides ores of copper, zinc and lead concentration is brought by this method.In this method, the advantage is taken of the preferential wetting of the ore by an oil.The finely ground ore is taken in a tank containing water and 1% of pine oil or turpentine oil.
Read More2016-10-12 Copper sulphate had a significant effect on the maximum froth height obtained in static three-phase froth tests. Proposals to explain these observation are made. If the above-mentioned thing is taken into consideration, the role of $\ce{CuSO4}$ is to provide $\ce{Cu}^{2+}$ which will act as an activator in the manner explained above.

Flotation is the most common concentration process used by the mineral industry, both in quantity of ores processed and in diversity of applications (Peres et al, 2007).At present, over 2 x 10 9 t per year of ore is estimated to be processed through flotation. In Brazil, this technique played an important role in the growth of the mineral sector, especially in the industry of ...
Read More2021-10-31 Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out. The process of froth floatation starts with the Comminution process in which the surface area of the ore is increased. The ores are crushed into very fine powder sized particles and mixed with water.

Crude ore is ground to a fine powder and mixed with water, frothing reagents, and collecting reagents. When air is blown through the mixture, mineral particles cling to the bubbles, which rise to form a froth on the surface.
