The lead reduction smelting process involves two-steps: a fusion of the ore material with lead in a carbon-rich environment, followed by the separation of silver from the lead in an oxygen-rich environment. Period
During this process, the ore, which may contain only 5% lead, is upgraded to a concentrate with about 50% lead. At Broken Hill, concentrate grades average about 70% lead, mainly because the relatively coarse grain of the ore allows excellent recovery of lead …
The ore concentrating process requires pine oil, alum, lime, and xanthate. Limestone or iron ore is added to the lead ore during the roasting process. Coke, a coal distillate, is used to further heat the ore.
Extracting the lead materials from the ore is a multi-step process. First the lead ore is ground into small particles that are less than 0.1mm, giving the ore a texture similar to table salt. Next the lead powder is put through a flotation process, that involves mixing the lead ore with water, the addition of pine oil and the introduction of ...
