Top

A concentrate is a form of substance which has had the majority of its base component (in the case of a liquid: the solvent) removed. Typically this will be the removal of water from a solution or suspension such as the removal of water from fruit juice. One benefit of producing a concentrate is that of a reduction in weight and volume for transportation as the concentrate can be re-constituted at the time of usage by the addition of the solvent.

Other

Concentrate can also be the residue valuable metal from which most of the waste rock has been removed. The residue metal becomes the raw material for smelting.
