Battery Scrap Recycling

We at Gravita Senegal practice Eco–friendly Recycling Techniques for various sources of Lead Scrap. We import Scrap Battery Plates / Battery Scraps for production of Remelted Lead.

Process
Our Lead Recycling plants employ Pyrometallurgical processes. In this process, Lead metal content is charged into a furnace together with appropriate fluxes & reducing agents. Reduction of Lead bearing material to crude Remelted Lead takes place along with the formation of Lead bearing slag. The slag may be collected and smelted in a separate slag campaign in the same or another furnace.

The molten metal and the dross are removed from the furnace by tapping operation into moulds or ladles. Normally the furnace metal is directly cast into ingots and these ingots are allowed to solidify. If required the metal is tapped directly into a holding kettle which keeps the metal molten for refining.

Local exhaust ventilation is provided for lead fumes and dust emissions at the lead and slag tap, launders, moulds, ladles, and refining kettles. This exhaust is taken to bag-house. Thus the system is Eco-friendly in all aspects.

Battery Recycling Process

Modern batteries are often promoted on their environmental qualities. The Lead-acid battery has led the way in recycling. The automotive industry should be given credit in organizing ways to dispose of spent car batteries. In the USA, 98% of all Lead acid batteries are recycled. In comparison, only one in six households in North America recycles batteries.



         

The recycling process starts by removing the combustible material, such as plastics and insulation, with a gas fired thermal oxidizer. Gases from the thermal oxidizer are sent to the plant's scrubber where they are neutralized to remove pollutants. The process leaves the clean, naked cells, which contain valuable metal content.
The cells are then chopped into small pieces, which are heated until the metal liquefies. Non-metallic substances are burned off; leaving a black slag on top that is removed with a slag arm. The different alloys settle according to their weights and are skimmed off like cream from raw milk.
