methods begin with the elimination of most of the sulfur in the concentrate through a roasting process, which is described below. A generalized process diagram depicting primary zinc smelting is presented in Figure 12.7-1. Roasting is a high-temperature process that converts zinc sulfide concentrate to an impure zinc oxide called calcine.
