The third and final phase in the processing of lead ore to metallurgical lead, the refining of the bullion in cast iron kettles, occurs in five steps: 1) removal of antimony, tin and arsenic; 2) removal of precious metals by Parke's Process, in which zinc combines with gold and silver to form12.6 Primary Lead Smelting 12.6.1 General15 Lead is found naturally as a sulfide ore containing small amounts of copper, iron, zinc, precious metals, and other trace elements. The lead in this ore, typically after being concentrated at or near the mine (see Section 12.18), is processed into metallurgical lead at 4 facilities in the U. S.12.6 Primary Lead Smelting - US EPALarge amounts of lead slag are produced during the production of primary lead and secondary lead. Considering lead concentrate smelting as an example, a primary lead smelting system production of 1 t of lead will discharge 7100 kg of lead slag (Hou, 2011).At the secondary lead recycling process, for each ton of metallic lead produced, 100–350 kg of slag are generated (Kreusch et al., 2007).A review on lead slag generation, characteristics, and utilizationاحصل على السعر
