In the flotation process, a mixture of water, minerals, and a flotation agent (also known as a collector) is agitated to create a stable froth of bubbles. The flotation agent helps to form a stable froth of air bubbles, which attach to the mineral particles and cause them to rise to the surface, where they can be collected.
