lead ore smelting method:

Lead Smelting Base Metal Smelting

Roasting is a method where a sulfide ore (i.e an ore containing PbS) is heated in air which converts the metal sulfide to either a metal oxide or a metal itself [3]. Word Equation: Lead (II) Sulfide + Oxygen à Lead (II) Oxide + Sulfur Dioxide. Chemical Equation: 2PbS + 3O 2 à 2PbO + 2SO 2.

Lead ores are such that these two operations are best combined into one simultaneous roasting-sintering process that produces a sinter ready for the lead blast furnace. The second stage of smelting can take place in an ore hearth, or a larger blast furnace.

The most common ore is zinc blende (ZnS), which is found in association with lead, iron, and other sulfides. Before smelting,zinc sulfide is usually concentrated by a float and sink method. The zinc sulfide is then roasted to form zinc oxide, followed by reduction with carbon and/or carbon monoxide.

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
