Percent recovery refers to the amount of the original substance retained after the completion of the reaction. In a recrystallization reaction, the original substance is recrystallized, after which, its recovery value can be computed.
calculating mining recovery (f t)/(c t), the % Metal Recovery can be calculated from assays alone using 100(c/f)(f t)/(c t). (c) % Metal Loss is the opposite of the % Metal Recovery, and represents the material lost to the tailings. It can be calculated simply by subtracting the % Metal Recovery from .
