Galena is a major source of lead ore. Missouri is the nation's top producer of primary lead ore, and the United States ranks third in the world behind China and Peru for production. In 2019, the U.S....
Abstract. Galena is the principal ore mineral for lead industry and the production of lead and its alloys. The industrial processing of galena includes its oxidized roasting to lead oxide, followed by reduction smelting of lead oxide agglomerate with coke in the blast furnace to commercial lead. The present work reports a thermal analysis …
Transcribed image text: Galena (PbS) is the ore from which elemental lead is extracted. In the first step of the extraction process, galena is heated in air to form lead (l) oxide. 2PbS (s) + 30 2 (g) ---> 2PbO ( s ) + 250 2 (g) AH = -827.4 kJ 1) When this reaction occurs will the surroundings feel hot or cold?
Lead(II) sulfide can be roasted in air at high temperatures to form lead(II) oxide and sulfur dioxide. Lead oxide can be further reduced with carbon to lead metal. 2 PbS + 3 O 2 → 2 PbO + 2 SO 2 PbO + C → Pb + CO 2 PbO + C → 2 Pb + CO 2 Physical. Lead(II) sulfide is a black solid, insoluble in all solvents.
