Lead concentrate is essentially a mineral called galena, which predominantly contains lead and sulphur. Smelting converts this into a metallic lead form.

The technology of Nyrstar&#;s lead smelting process includes top submerged lance (TSL) furnace, blast furnace, lead refinery, slag fuming, electrowin copper, and solvent extraction/electrowin (SXEW).

TSL and blast furnace process

The top submerged lance (TSL) and blast furnace operations are the actual smelting part of the process and involve the high temperature reduction of sinter with metallurgical coke to produce a crude lead bullion and slag. Lead bullion contains small amounts of other metals including silver, gold and copper.

All of these elements are extracted from the lead during the various refining processes and become valuable marketable metals.

Two Grades Primary Lead (Nyrstar BHAS) are registered in the London Metal Exchange (LME).
