2ZnS 3O 2ZnO SO2 (1) - US EPA

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.

Zinc processing | Britannica.com

Apr 12, 2019· Complex sulfide ores have to be sintered, but oxidized residues such as zinc ashes and drosses recovered from galvanizing processes, oxides produced from low-grade residues, lead smelter dusts, and steel-mill dust high in lead and zinc can bypass the sinter roasting process.

What is Sintering? - Definition from Corrosionpedia

Sintering is a heat treatment process in which a large quantity of loose aggregate material is subjected to a sufficiently high temperature and pressure to cause the loose material to become a compact solid piece. The amount of heat and pressure administered during the sintering process is slightly less than the material's melting point.
