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.

Razão de concentração (beneficiamento)
A razão de concentração responde: quantas toneladas de minério bruto entram na usina para sair uma tonelada de concentrado? RC = massa de alimentação / massa de concentrado. É uma medida do grau de upgrade que o beneficiamento promove: um minério pobre, com pouco metal disperso em muita ganga, tem razão de concentração alta (muitas toneladas processadas por tonelada de produto); um minério rico, razão baixa. O número é essencial no balanço de massa da usina — junto com os teores de alimentação, concentrado e rejeito, ele fecha as contas e permite dimensionar moinhos, células de flotação e a disposição de rejeitos. Informe a massa de alimentação e a de concentrado.

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.
Sludge Recycle Ratio
Calculate the sludge recycle ratio (R) of an activated-sludge system by mass balance, R = X ÷ (X_r − X), from the mixed-liquor suspended solids (MLSS) and the return sludge concentration. The result (dimensionless, or ×100%) gives the fraction of influent flow that must be recycled from the secondary clarifier to keep the desired biomass in the reactor. Typical ratios range from 0.25 to 1.0. Enter the reactor MLSS and the return sludge concentration.
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.
