Froth flotation is used to separate commercially essential minerals from other minerals and impurities in mining ore or mining minerals. In this case, minerals are found on the surface of a thick froth layer, which is also known as the "froth layer.". This process is called "floatation.". In this process, good minerals are separated ...

In 1924, fatty acid soap flotation of oxidized ore was invented. In 1925, xanthate was used for flotation of sulfide ore, its dosage was a few 101000ths of ore weight, and the particle size of the separated material was reduced to 10 μm to the minimum, which allowed major development of industrial application of flotation.
