LEAD SMELTING PROCESS - COMINCO LTD,CA

The earliest known process for smelting lead sulphide ore involved oxidizing the ore on an open grate. The principal reactions taking place in such a smelting operation are as follows: PbS + O 2 = Pb + SO 2 I 2PbS + 3O 2 = 2PbO + 2SO 2 II

Lead: smelting, producing and classification-Metalpedia

Lead ores are such that these two operations are best combined into one simultaneous roasting-sintering process that produces a sinter ready for the lead blast furnace. The second stage of smelting can take place in an ore hearth, or a larger blast 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-

A Dynamic Thermochemistry-Based Process Model for

2021-6-15  In the smelting stage of the present metallurgical process, one aims to convert a lead ore concentrate into a lead-oxide-based slag and a lead bullion. This is accomplished by blowing O 2-enriched air just below the surface of the oxide slag. In the second stage of the process, not to be treated in the scope of the present work, after tapping ...

Lead processing - Mining and concentrating Britannica

Before lead concentrate can be charged into traditional blast furnaces for smelting, it must be roasted to remove most of the sulfur and to agglomerate further the fine flotation products so that they will not be blown out of the blast furnace. Various fluxing materials, such as limestone or iron ore, are mixed with the ore concentrate.

Smelting of Lead Ores using High Lime Slags

2017-4-9  Lead as a collector of gold and silver from very rich oxidized ore has its advantages; the loss of gold and silver in the refining of the lead bullion is smaller than in the refining of copper matte, and when the ore contains sufficient lead it is the only process to adopt. Lead smelting requires not less than 12½ per cent, lead

Lead Smelting - an overview ScienceDirect Topics

Secondary lead smelting is such a hazardous process that priority should be given to automation of the transport and oven-filling phases. The preparation of all metal pigments, which is very hazardous when done by hand, becomes far less dangerous in closed, automated systems. Instead of dust-producing powders, liquid premixes are preferred.
