C = F/K = F (f — t) / (c-t) = the weight of the concentrate. Recovery % Represents the ratio of the weight of metal or mineral value recovered in the concentrate to 100% of the same constituent in the heads or feed to the process, expressed as a percentage. It may be calculated in several different ways, depending on the data available.

Gravity separation can be used for concentrating, also for tailing processing and preconcentration. In addition, gravity separation generally consists of a combination process with magnetic separation and flotation. The density of manganese oxide ore is generally about 3.7~3.9t/m3, which is significantly different from silicate type gangue.

In mining, tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction ( gangue) of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.
