Lead processing, Lead processing - Lead processing - Refining: To remove and recover remaining impurities from lead bullion, either pyrometallurgical or electrolytic refining is used; the choice between the two methods is dictated by the amount of bismuth that must be eliminated from the bullion and by the availability and cost of energy The Parkes zinc-desilvering process is the most widely used ,Lead Ore Smelting Plant Manufacturers and Turnkey Solutions, Lead Ore Smelting Plant The most important lead ore is galena (lead sulphide) Other important ores such as cerrusite (lead carbonate) and anglesite (lead sulphate) may be regarded as weathered products of galena Step -1 Lead ore is initially analyzed in lab Step-II Roasting or heating for some timeLead Smelting, The PSD shows the problem in attempting to produce lead in a single step The volatility of PbS and PbO make it desirable to keep the gas volume as low as possible (ie, use pure O 2 in smelting) But this means operating along the pSO 2 =1 isobar, thus producing a large amount of PbO-containing slag in order to produce a low-sulfur bullion Producing a low-sulfur bullion requires the use air ,Lead and Zinc, 6124 Lead Concentrate Sintering and Smelting Smelting is the process by which rough lead bullion is produced from lead concentrate After the ore has been concentrated at a mill near the mine, the lead concentrates are shipped to a smelter Here, in the case of galena, the first step involves removing the sulfur from the mineral RoastingRotary furnace for lead smelting, Lead smelting rotary furnace is widely used for the lead paste smelting of battery recycling plants all over the world The lead paste, lead grid or lead ore will have reduction reaction and become crude lead The crude lead can be sold directly or put into lead refining kettle/pot for further refining process and being casted into ingots.
