A separation process is a method that converts a mixture or solution of chemical substances into two or more distinct product mixtures. At least one of results of the separation is enriched in one or more of the source mixture39s constituents. In some cases, a separation may fully divide the mixture into pure constituents.

Separation processes are based on the theory of vaporliquid equilibrium. This theory states that streams leaving a stage in a separation process are in equilibrium with one another. The idea of equilibrium revolves around the idea that when there is vapor and liquid in contact with one another they are in constantly vaporizing and condensing.

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.

Potash Flotation. The conditioner and reagentized saltbrine slurry is floated in a SubA Flotation Machine. In the circuit shown, roughing is accomplished in a SubA Free Flow Flotation Machine with no intermediate weirs or feed pipes. This allows the coarse sodium chloride waste product to flow through the machine unmolested.
