USES OF LEAD

CN104087756A Secondary lead redox smelting method

The invention discloses a secondary lead redox smelting method which comprises the following steps: crushing scrap lead storage batteries, separating to obtain a lead plaster, drying the lead plaster in a drying kiln, blending with sulfur, carrying out oxidation reaction to obtain lead-rich slag, carrying out reduction reaction on the lead-rich

Chemical Reactions of Lead Smelting Base Metal Smelting

A major and primary Lead mineral is galena (chemical formula = PbS) which comprises of 86.6% of Lead [1]. In order to smelt this mineral, a blast furnace is needed to be used. A blast furnace is an enormous oven which is used to accomplish the smelting processes [2].

Lead: Secondary Lead Smelter eTool Definitions

Secondary lead smelting Secondary smelting produces lead and lead alloys from lead-bearing scrap metal. Raw materials used in secondary lead smelting include scrap automobile batteries, wheel balance weights, pipe, solder, drosses, and lead sheathing.

Lead processing , Britannica

The recycling of lead from battery scrap involves treating and separating the scrap, reducing and smelting the lead-containing fractions, and refining and alloying the lead bullion into a commercial product. It is usually conducted in reverberatory and blast furnaces at refineries devoted exclusively to handling secondary lead and lead alloys. However, some primary refineries also refine

Fundamentals of the Recycling of Lead Acid Batteries

produce secondary lead. The informal sector, in contrast, often only uses the metallic parts of old batteries (grids, terminals, bridges) to produce articles such as solders or weights for fishing nets. The other parts of the battery are simply dumped in the environment. Even industrial recycling facilities in developing countries employ many manual techniques due to cheap labour. Batteries
