Metal Blanc Bourg-Fidèle - France

The next stage of the process consists in extracting the lead from the metallic materials and oxides obtained from the crusher, by melting them with an oxy-gas burner and reducing them chemically by adding reducing agents in rotary furnaces.

The metal obtained is then directed to a refining unit.

The fumes and gas emitted during the process are transferred via a dry route through a complex sleeve filtration system. This system is made of 6 sleeve filters with a total output of 342.000 Nm3/h, for a filtering area of 4322 m², i.e. 2030 filtration sleeves.
