In large-scale operations this is accomplished by taking advantage of the different properties of the minerals to be separated. These properties can be colour optical sorting , density gravity separation , magnetic Mineral processing - WikipediaFroth flotation is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp. In the process, hydrophobic particles become bound to the surface of the bubbles.
