Froth Flotation Process
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.
Froth Flotation
where r is the measured cumulative recovery of either valuable or gangue at time t, R is the calculated equilibrium recovery as t → ∞, and K is a first-order rate constant of mass removal (units of time −1) that describes the shape of the time–recovery curve at small flotation times.Thus, each time-recovery profile can be characterized by two parameters, …

Ore Dressing
The extraction of raw minerals begins with the mining of rich ores, which are then cut up in crushers and grinders. The pieces of rock initially weighing tonnes are ground down to a few tenths of a millimetre. This grinding process, which often covers six decimal orders of magnitude of the particle size, is carried out in several steps.
