Question

describe the process involved in extraction of pure pb form galena​

Answer 1

Answer:

Lead is extracted from ores dug from under-ground mines. Of the more than 60 minerals that contain lead, only 3 galena, cerussite and anglesite are commercially viable. ... The resulting powder is further heated in a blast furnace, with carbon producing molten lead which is drawn off into lead molds.

Answer 2

Answer:

Roasting • The galena is roasted (reacts with O2) in order to remove the sulfur component of the metal sulfide. 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.
