The Queneau-Schuhmann-Lurgi (QSL) Process :: Total

The QSL process is one of a handful of promising lead processing technologies which counter act the drawbacks of the sinter plant - blast furnace methods currently in operation. A highly-efficient process, QSL produces lead from lead concentrates and secondary raw materials in one reactor and can cut the environmental impact in half when comparing conventional methods.

Lead processing - Mining and concentrating Britannica

The QSL, or Queneau-Schuhmann-Lurgi, process treats all grades of lead concentrates, including chemically complex secondary minerals, in a refractory-lined reactor into which oxygen and natural gas are blown through tuyeres at the bottom. The “green,” or unroasted, charge is first oxidized in a molten bath by the submerged oxygen injection; this produces a flue gas carrying oxides of lead and zinc as
