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 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.
