Thanks a lot.Lead and zinc ores usually sphalerite, ZnS often occur together and may also contain silver, copper and gold. The ore has first to be separated from clays and other silicates gangue after which the lead ore and the zinc ore are separated.

In the pyrometallurgical process, ore concentrate containing lead, zinc, or both is fed, in some cases after sintering, into a primary smelter. Lead concentrations can be 50-70, and the sulfur content of sulfidic ores is in the range of 15-20.Jul 31, 2015 The two metals are closely connected, starting with their mineralogical occurrence in combined lead-zinc ores i.e., combination of mainly lead sulfide, zinc sulfide, iron sulfide, iron carbonate, and quartz that are processed in the primary industry and hence interlink the production routes. Both metals have very high recycling rates.The zinc-lead blast furnace. Sintered zinc and lead concentrates, mixed with metallurgical coke, are charged into the top of a shaft furnace, into which preheated air is blown through nozzles, or tuyeres, at the base see figure.

Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface. Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist.

Consequently, a refining waste slag is generated during the refining of the crude bismuth by chlorine Xiong and Xiao, 2005. This slag is unacceptable to lead smelters because the lead in the slag mainly exists in the form of lead chloride, which is volatile at temperature of lead smelting and thus refractory.They produced not only gold and silver, but zinc, copper, and lead, all essential for the eastern Industrial Revolution. Soon the West was filled with neer-do-wells hoping to strike it rich. Prospecting. Few were so lucky. The chances of an individual prospector finding a valuable lode were slim indeed.with a view to recovering zinc from lead blast furnace slag. In earlier attempts, the idea of reducing zinc oxide to metallic zinc and then to fume was abandoned after trying compressed air blast without fuel. In 1925, the Waelz process of treating oxidised zinc ores for the recovery of zinc oxide was started in Germany.

Charges to the furnace are lump sinter, hot briquettes, and coke. Slag and lead are continuously tapped from the bottom of the furnace into a forehearth where separation occurs.Lead and zinc are formed in the same types of ore deposits. More than seventy six percent of the lead consumed annually is used to make batteries for cars, trucks and other vehicles.Nearly all zinc sulphide ores carry some lead the western ores of zinc generally carry silver, and some of them carry both silver and gold. Pyrite, pyrrhotite, chalcopyrite, and galena are very commonly associated with sphalerite in sulphide deposits. The most common gangue minerals are quartz, calcite, and dolomite.
