The grade is a measure of quality and it captures concentration levels (i. e., how pure a certain fraction is). If grade captures quality, then Recovery is a measure of quantity: it describes how much of certain material in the input stream is made available for reprocessing. A recovery of R% means that (100 - R)% of the material going into the process is lost, ending up either in mine tailings or as a contaminant in one or more fractions. By weight, copper wire contains about 70% copper and 30% PVC. Suppose we process 1 ton of wire per hour into a copper fraction of 0.74 ton/hour, of which 0.69 is copper and 0.05 is PVC. What is the weight and composition of the tailing?
