MEI Blog: Froth Flotation. Why is it still so intensively ...

Apr 10, 2013· But explaining the principle of froth flotation is not too difficult- you add chemicals to a mixture of ground ore particles and water, which makes the valuable particles 'greasy' and thus water repellent. ... However it would be remiss to exclude the very primary stage that the comminution circuit sets for this flotation process. As many ...

Froth flotation - Wikipedia

Before froth flotation can work, the ore to be treated is reduced to fine particles by crushing and grinding (a process known as comminution) so that the various minerals exist as physically separate grains.This process is known as liberation.The particle sizes are typically less than 0.1 mm (100 µm), but sometimes sizes smaller than 7–10 µm are required.

Flotation | Centre for Minerals Research

Froth flotation is the follow-on operation, after comminution and classification, in the process of liberating and separating minerals by exploiting the differences in physical properties of the different minerals that make up an ore. Froth flotation is achieved when particles are separated based on their surface potential.

Mineral processing - Wikipedia

Froth flotation is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp.

Comminution - Wikipedia

Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earth's crust.

Control of Comminution Circuit for Efficient Froth ...

Efficiency of seperation in the froth flotation circuit is very much dependent on the efficiency of size reduction and size seperation in the preceeding comminution classi-fication circuit. A coarser grinding product than desired causes loss of grade or recovery due to inadequate libe-ration where as with over grinding there is an increase in slime loss. this paper ennumerates the factors that ...
