Lead Ore Smelting Plant

Product Description

Mettherm provides equipment for Lead Ore Smelting Plant for processing of lead bearing material from Battery scrap.

The lead grids, lead oxide and other lead parts are cleaned and then melted together in smelting furnaces. The above raw materials, along with soda ash, iron turnings and charcoal are charged into Rotary furnace for smelting purpose.

The converted/melted lead is tapped out as crude lead blocks. Slag is separately treated in Rotary Furnace for further recovery. Emissions due to smelting are taken to Air Pollution Control system. The air pollution control plant, comprises of dust collectors, cyclones, wet scrubbers, cooling towers, bag-house filtration units, induced draft fans wet and a chimney.

Lead Ore Smelting Plant

The most important lead ore is galena (lead sulphide). Other important ores such as cerrusite (lead carbonate) and anglesite (lead sulphate) may be regarded as weathered products of galena.

Step -1
Lead ore is initially analyzed in lab.

Roasting or heating for some time . PbS is converted into Pb through following reactions:
PbS + Fe => Pb +FeS or PbS + 2PbO => 3Pb + SO2 PbS + PbO2 => 2Pb + SO2 The above mentioned chemical reactions are sum reaction. That means that there are no intermediate steps in between. The reactions take place in the melting furnace at high temperature (1000-1200° C) and need additives, which are carbon (in the form of coal) and iron (in the form of iron swarf). Impurities are collected in the slag which requires, for example soda ash as liquidifying and slag forming constituent. It requires, however, a much higher furnace operation temperature of approximately 1250°C to 1400°C. Lead recovered is subject to refining in lead refining furnaces.
