Chapter 6 Copper Production Technology - Princeton University

Table 6-6 summarizes the four types of solution mining. Vat, heap, and dump leaching are methods of hydrometallurgical processing of mined ore (see figure 6-13). Thus they are complements, not alternatives, to underground or open pit mining. In situ leaching is a stand-alone mining method (see figure 6-14).

This means that 95.7% of the copper present in the ore was recovered in the concentrate, while the rest was lost in the tailings. (c) The % Cu Loss can be calculated by subtracting the % Cu Recovery from 100%: % Cu Loss = 100 – 95.7 = 4.3% This means that 4.3% of the copper present in the ore was lost in the tailings.
