Selective leaching of base metals from copper smelter

2010-6-1  Based on equivalent calculations, 15.2 g sulfuric acid is the stoichiometric amount required to leach the base metals from 20 g of the slag, but the recovery of cobalt and copper is nearly 3% better when using 17.6 g sulfuric acid. Of course, whilst higher concentrations of sulfuric acid is beneficial for the leaching process, excess acid (above stoichiometric) requires the consumption of more calcium hydroxide to neutralize and the amount of leach
