MetallurgyTechniques - Lead from Battery Scrap

Type of Technology : Indigenous

Area of Technology

1. Materials and Material Science, 2.Chemistry and Chemical Ebgineering

Brief Description

Battery scrap is mixed with reduction and fluxes. The mixture is compacted to form briquette followed by smelting in the furnace to recover lead. The process recovers above 90% lead metal with metal purity around 98%.

Major raw materials

Battery Scrap, reduction, Charcoal and Fluxes

Major Plant Equipment/Machinery

Rotary furnace with dust catching arrangements, mixer, briquetting press etc.

Area of Application

Minerals, Metals and Materials

Applications

Battery and chemical engineering industry, Paint industry

Status of Development : Ready for commercial use

Ecological/Environmental Impact

(i) Sulphur in the battery scrap is converted to sulphide and can be used for manufacturing H₂S (ii) Dust catching arrangement is essential

Patenting details : Patent fied

Technology Transfer Assistance Offered

(a) Process know how (b) Detail of equipment (c) Plant lay out (iv) quality assurance methods. Assistance can be provided at the time of production or trails on separate terms and conditions.

Additional Information

A plant and equipment with capacity to process 3t/day battery scrap costs approximately Rs. 30.0 Lakhs
