Abstract
The sulphation roast-leach process for complex sulphides results in phase changes due to roasting and leaching. The phases in the calcine, and in the neutral and hot acid leach residues were identified and their degree of liberation determined in order to design and Interpret separation tests on the residues. The hot acid leach residue was composed of hematite, silica, and lead sulphate with some associated silver. Magnetic separation was selected as the process for producing a lead concentrate, as the non-magnetic product. Separation was limited by -1 pm hematite reporting to the product, and hematite/lead sulphate agglomerates reporting to the magnetics.
