froth floatation mixtures

Introduction to Mineral Processing

Froth flotation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer.

In this sense, mining froth can be described as an aerated slurry that either occurs naturally or, in some cases, purposely created to assist with the separation of minerals. Froth flotation is an important step used for the recovery and upgrading of sulfide ores, allowing far more economic recovery of valuable metals from much lower grade ore.

What is Froth Flotation?

Aug 21, 2019 · Froth flotation is a process using air bubbles to separate materials based on their relative affinity to water. Bubbles carry reagent and hydrophobic materials to the top of a tank where they can be removed. Froth flotation has been used for more than a century in mining operations to separate valuable materials from excavated ores.

Feb 29, 2008 · Best Answer: Froth flotation is a selective process for separating minerals from gangue by using surfactants and wetting agents. The selective separation of the minerals makes processing complex (that is, mixed) ores economically feasible. The flotation process is used for the separation of a large range of sulfides, carbonates and oxides prior to further refinement.
