Zinc Smelting an overview | ScienceDirect Topics

It consists of two sub-processes, lead-zinc sinter and imperial melting (Xiaoying Liu, 2003), while zinc and lead are smelted simultaneously in a vertical furnace, with unrefined lead tapped from the bottom, and zinc recovered through the condensation of zinc vapor from the top of the furnace.

Lead and Zinc Smelting IFC

Lead and Zinc Smelting Industry Description and Practices 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

Zinc: smelting, producing and classification-Metalpedia

Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. The most common zinc concentrate processed is zinc sulfide, which is obtained by concentrating sphalerite using the froth flotation method. Secondary (recycled) zinc material, such as zinc oxide, is also processed with the zinc sulfide.

Copper, Lead and Zinc Smelting and Refining

Calcining, or roasting, is a high-temperature process (700 to 1000 °C) that converts zinc sulphide concentrate to an impure zinc oxide called calcine. Roaster types include multiple-hearth, suspension or fluidized-bed. In general, calcining begins with the mixing of zinc-containing materials with coal.

Zinc concentrate internal circulation technology for

We obtained the production parameters from a zinc smelter located in the middle state of China. The zinc production line with an annual output of 100,000 ton needs to input ~198,000 ton of zinc concentrated ore for smelting. The flue gas flow generated by this production line is about 60,000–70,000 m 3 ·h −1.
