Lead - Essential Chemical Industry

Lead for recycling may be in the form of scrap metal (roofing sheet, for example), or compounds of lead, such as the pastes from lead-acid batteries. Clean metallic lead can be melted and refined directly, but compounds and lead alloys require smelting, using processes similar to those used with lead ores. Two-stage process

LEAD SMELTING PROCESS - COMINCO LTD,CA

The present invention relates to an improved process for the smelting of lead sulphide ores and concentrates. The earliest known process for smelting lead sulphide ore involved oxidizing the ore on an open grate. The principal reactions taking place in such a smelting operation are as follows: PbS + O 2 = Pb + SO 2 I 2PbS + 3O 2 = 2PbO + 2SO 2 II

Lead: Secondary Lead Smelter eTool

Smelting is the process of reducing reclaimed lead compounds to elemental lead. Respiratory protection and medical surveillance are not addressed in this eTool. However, they are essential for controlling lead exposure levels and preventing lead-related disease when engineering controls do not reduce airborne lead levels below the permissible exposure limit.

The products of the smelting ISASMELT™ process are tapped from the bottom of the furnace through a water-cooled taphole. Tapping of the furnace is by semi-automated machinery. The furnace can be tapped intermittently or continuously. The products flow into a settling furnace, where the matte or metal separates from the slag.
