Metallurgical Recovery
Compute the metallurgical recovery of a processing plant, R = (metal in concentrate / metal in feed)·100%, the fraction of the metal contained in the ore that is actually recovered into the concentrate. It is the key measure of plant efficiency: the unrecovered metal is lost in the tailings. Small recovery gains represent large value in large-scale operations. Enter the mass of metal in the concentrate and in the feed.

Recuperação metalúrgica
Depois de lavrado, o minério vai para a usina de beneficiamento, onde o metal é separado da ganga. A recuperação metalúrgica mede a eficiência desse processo: R = (metal no concentrado / metal na alimentação)·100%. O metal que não é recuperado escapa no rejeito e se perde para sempre. Por isso, numa grande mina, ganhar 1 ponto percentual de recuperação pode valer milhões por ano — e justifica enormes investimentos em flotação, moagem fina e reagentes. A recuperação caminha junto com o teor do concentrado: empurrar uma costuma sacrificar a outra, e o ponto de equilíbrio é uma decisão econômica. Informe a massa de metal no concentrado e na alimentação.

Mass Recovery
Calculate the mass recovery (mass yield) of a mineral processing operation, R = (concentrate mass ÷ feed mass) × 100%, dividing the concentrate mass produced by the ore feed mass. The result, in %, is the fraction of mass reporting to the concentrate — different from metallurgical recovery (which measures the fraction of metal recovered). Low mass recovery is typical of lean ores (little concentrate from much feed); high indicates rich ore or poorly selective concentration. Combined with the grades, it closes the plant's mass balance. Enter the concentrate and feed masses.
Concentration Ratio
Compute the concentration ratio of a processing operation, CR = feed mass / concentrate mass, how many tonnes of raw ore are needed to produce one tonne of concentrate. It measures the degree of upgrade: high ratios indicate lean ores that require heavy processing. It is useful in the mass balance and plant sizing. Enter the feed mass and the concentrate mass.
Mining Recovery
Compute the mining recovery, R = (mined ore / in-situ ore)·100%, the fraction of the ore originally present in the deposit that is actually extracted. Not all ore is recoverable: support pillars, blasting losses and contacts leave part behind. Together with dilution, it defines the extraction efficiency and the mineable reserves. Enter the mined ore and the in-situ ore.
