Froth flotation to separate plastics, Argonne National Laboratory Froth flotation cells to concentrate copper and nickel sulfide minerals, Falconbridge, Ontario. Froth flotation is a process for separating minerals from gangue by exploiting differences in their hydrophobicity.
Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation, classification, magnetic separation and leaching. Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold.
The process thus in its essence is similar to distillation, however the material which is condensed on the cooler surface then has to be removed mechanically, thus requiring different laboratory equipment. Bioleaching is the extraction of metals from their ores through the use of living organisms. Separation process. From Crystallization
A separation process is a method that converts a mixture or a solution of chemical substances into two or more distinct product mixtures, [1] a scientific process of separating two or more substances in order to obtain purity. At least one product mixture from the separation is enriched in one or more of the source mixture's constituents.
Foam separation is a chemical process which falls into a category of separation techniques called "Adsorptive bubble separation methods". [1] It is further divided into froth flotation and foam fractionation. Foam separation is essential in order to prevent contamination of fermentation medium through the foam by external microbes.
Foam fractionation is a chemical process in which hydrophobic molecules are preferentially separated from a liquid solution using rising columns of foam.It is commonly used, albeit on a small scale, for the removal of organic waste from aquariums; these units are known as "protein skimmers".

Traditional Dissolved Air flotation (DAF) mainly operates with bubble sizes ranging from 80 to 300 μm with very inhomogeneous bubble size distribution. Microbubble cloud in a Microflotation cell. A major difference of low pressure dissolved air flotation and other flotation processes lies in the volumes of bubbles, amount of air and raising ...
