Lead smelting and refining process - Strategic application technology
Oil and Gas Refining
By definition, crude oil and natural gas are the raw materials of the petrochemical industry, with inert gases such as N2 and CO2 already used on a large-scale during their extraction. The processing of crude oil to the desired end products involves several steps. Again, gases from Messer are used in many of these process steps.
Lead smelting and refining process
Lead is manufactured over several steps: The starting material, primary lead (lead-containing ores) or secondary lead (recycled, lead-containing waste, in particular spent batteries) is first prepared by roasting and/or physical processes. Subsequently, the starting materials are reduced in a melting furnace and freed from accompanying substances, whereby different melting processes are used depending on the starting material. The melted material is further freed from contamination in a refining process and poured into moulds, it is then available as raw lead for further processing.
