Froth Flotation - an overview ScienceDirect Topics
Froth Flotation. Froth flotation is a surface chemistry based separation process which is extensively used in the processing of mineral ore deposits as a method of separating the desired mineral component from their associated gangue material [17,34]. From: Advances in Colloid and Interface Science, 2005.

Depression behavior and mechanism of sodium silicate on ...
Flotation is the dominant method of rare earth beneficiation because of its high separation efficiency, high enrichment ratio and good for recovery of fine rare earth. Sodium silicate (SS), a commonly used inhibitor in rare earth mineral flotation, is widely applied in the bastnaesite flotation process to suppress calcium-bearing gangue ...

2021-10-20 Flotation responses in a micro-flotation cell were used to verify the adsorption of surfactin and to determine the change in surface characteristics, specifically hydrophobicity and hydrophilicity. These tests were also used to predict possible responses of coal particles to the addition of surfactin in a froth flotation process.
