Background of lead and zinc production. Galena (PbS) and sphalerite (ZnS) are the major ore minerals for Pb and Zn respectively. Pyrometallurgical processing of Pb and Zn metals usually includes four stages: ore dressing, smelting, drossing and refining. Sinter – blast furnace route is one of the most important smelting technologies which …

Kazakhstan. Kentau was formed on the site of a workers' camp in 1952. Polymetallic ores from the Mirgalimsai deposit, containing mainly lead and zinc, as well as other associated metals, were actively mined near the town from 1942 to 1994. The average metal content in the ore was lead (1.81–1.89%), zinc (0.63%), copper (0.01%),

Lead and zinc can be produced pyrometal- lurgically or hydrometallurgically, depending on the type of ore used as a charge. In the pyromet- allurgical process, ore concentrate containing lead, zinc, or both is fed, in some cases after sin- tering, into a primary smelter. Lead concentra- tions can be 50–70%, and the sulfur content of sulfidic ...

Zinc ores normally contain 5–15% zinc. Approximately 80% of zinc mines are underground mined, 8% are mined from open pits, and the remainder are a combination of both ores ( Ray et al., 2014 ). Zinc concentrate, which contains approximately 55% zinc, is roasted at a temperature approximately 800°C (1472°F).
