lead ore smelting process

How lead is made material used processing product History of lead mining Minerals and mines Foundations

Besides the ore itself only a few raw materials are necessary for the refining 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 The 19th century was a period which saw Cornish mining technology used to deepen some of the mines in search of richer ore deposits However as the lead veins narrow with depth this proved unsuccessful and attention was switched to resmelting the lead rich waste slag and slimes left over from previous medieval mining
