Mineral processing is the art and technology of treating ores from the mining areas in order to separate the valuable minerals from the waste rock. It includes processes to provide a more concentrated material for the procedures of the following extractive metallurgy. The two main processes to increase the concentration of minerals are leaching and flotation.

Flotation has now become the most widely used process for extracting many minerals from their ores. Most kinds of minerals require coating with a water repellent to make them float. By coating the minerals with small amounts of chemicals or oils, finely ground particles of the minerals remain unwetted and will thus adhere to air bubbles.
