QSL Technology :: ECOBAT Technologies :: LEADERS IN LEAD

ECOBAT operates the largest lead smelter in Germany. The primary lead smelter BBH Stolberg relies on the environmentally friendly and energy-saving technology of the QSL process, which was introduced in 1990. Here, lead is won by charging lead concentrates and secondary raw materials to a single, self-contained aggregate, the so-called QSL reactor.

Smelting - Wikipedia

Smelting is a process of applying heat to ore in order to extract a base metal.It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.
