We
at Gravita Ghana Ltd. 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.
Typically, in this process, Lead bearing materials are 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 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.
The molten metal and the dross are removed from the blast 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.
