Raw materials for recycling
lead are waste batteries, and the major resources
are domestic vehicles,
industrial companies using batteries for preliminary
sources of electricity, telephone offices under
KT Corp.,
the Korea Maritime and Port Administration, Korea
Railroad Corp., Korea Coal Corp., and substations
under Korea Electric Power Corp. Waste batteries
are classified into the specific industrial wastes.
Composition materials of waste battery are grid,
oxide, P.P., separator, and electrolyte, and the
materials
to be produced from recycling lead are grid and
oxide.
Waste batteries are separated to paste, grid,
P.P. and separator through the process of primary
electrolyte
removal and crushing, and the separated paste
and grid are inputted into melting furnace (rotary
furnace)
by mixing with soda ash, fine iron, and fine coal,
and then pass through reduction and casting processes
in
the fixed time.
Pure lead and lead alloy (Sb lead, Ca lead) are
produced through the processes of refining and
alloying of
unwrought lead produced by the drossing process
in the kettle for melted lead. |
