5.1.7.3 Iron. Although iron is not leached as a desired mineral, it is often extracted during the extraction of other metals. ... The second operation is metal extraction by leaching. General flow sheets for typical aqueous precious metal extraction will be presented in Chap. 10. 5.3.1 Cyanide Leaching.
The iron in the chalcopyrite ends up converted into an iron(II) silicate slag which is removed. Most of the sulfur in the chalcopyrite turns into sulfur dioxide gas. This is used to make sulfuric acid via the Contact Process. An overall equation for this series of steps is: [2CuFeS_2 + 2SiO_2 +4O_2 rightarrow Cu_2S + 2FeSiO_3 + 3SO_2 label{1} ]
The total extraction efficiency of Li2O was 87.3%, including the extraction efficiency of Li2O leached into liquid phase, 7.6%, and converted into Li2SiO3, 79.7%, obtained under optimal conditions ...
