(MERAF) for the Base Metals Smelting Sector - CCME

4.2.2. World Bank
The World Bank has set guidelines 134 for emissions from:
• copper smelting (Table 33);
• lead and zinc smelting (Table 34); and
• nickel smelting and refining (Table 35).
Table 33: World Bank Guidelines for Emissions from Copper Smelting
Parameter Maximum Value (mg/Nm 3 )
SO 2 1,000
Arsenic 0.5
Cadmium 0.05
Copper 1
Lead 0.2
Mercury 0.05
Particulate Matter – Smelter 20
Particulate Matter - Other 50
The guidelines indicate that modern plants using good industrial practices should
set as targets total dust releases of 0.5-1.0 kg / t of copper and SO 2 discharges
of 25 kg / t of copper.
The guidelines indicate that the double contact double adsorption plants should
emit no more than 0.2 kg of sulphur dioxide per ton of sulphuric acid produced
(based on a conversion efficiency of 99.7%).
