Flotation has been developed as the principal separating process for the potash salts which generally are coarsely crystalline and free from the sodium salts at about 10 to 14 mesh. In most cases the potash is floated in the froth product and the salt, NaCl, discarded as tailings. A plus 60% K2O product is required and flotation normally will ...

Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out. This is a method of mineral processing in which different minerals are separated selectively. The ores containing multiple metals, such as lead, copper and zinc, can be selectively extracted by using froth floatation.
