Gravita is committed to the employment of environment friendly technologies in our solutions for the used Lead Acid Battery Recycling and Battery Manufacturing Industries, covering Secondary Lead Smelting, Lead Refining, Lead Alloying & Lead Oxides Manufacturing and Lead Pollution Control.
Our Battery Recycling Plant employ pyrometallurgical processes. Typically, in pyrometallurgical Secondary Lead Smelting, Lead Bearing Battery Materials are charged into a furnace together with appropriate fluxes & reductants, drosses, returning slags and process dusts for smelting. Reduction of Lead bearing material to crude Soft/Antimonial 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.
Mostly Blast / Tilting Rotary Furnaces are used, either singly or in different combinations, for single/multi stage smelting. The process employed, furnace combination, fluxes, reductants etc. are finalized taking into account the required plant capacity, required product mix, pollution control plant and environmental concerns, the desired level of flexibility in plant operation and the composition of available battery scrap. Kettle furnaces are used for refining and alloying operations.
