Chapter 6 Copper Production Technology
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).
