Zinc Part 1

Zinc ore is no longer mined in Germany today, and the zinc concentrations in the deposits are too low for cost-effective zinc extraction. The raw material for zinc extraction has therefore traveled a long way, for example, from Australia - mostly by ship - before it is processed into zinc metal in Germany.

Lead smelting

Plants for the production of lead are generally referred to as lead smelters. Primary lead production[clarification needed] begins with sintering. Concentrated lead ore is fed into a sintering machine with iron, silica, limestone fluxes, coke, soda ash, pyrite, zinc, caustics or pollution control particulates. Smelting uses suitable reducing ...

How zinc is made

2 Zinc can be produced by a process called froth flotation, which is also used for reduction of copper and lead ores. This process involves grinding the zinc ore to a fine powder, mixing it with water, pine oil, and flotation chemicals, and then agitating the mixture to "float" the zinc to the surface.

Zinc processing

The zinc content of mined ore is usually between 3 and 10 percent. Almost all ores contain the lead sulfide mineral galena and small quantities of cadmium sulfide. Chalcopyrite, and copper-iron sulfide, is often present. The most common gangue constituents are calcite, dolomite, and quartz.
