The silver extraction process - extract lead from galena
The ore mineral galena (PbS) contains essentially no uranium and thorium. Its lead isotopic composition is defined by 206 Pb (derived from 238 U), 207 Pb (derived from 235 U), 208 Pb (derived from 232 Th), and 204 Pb (stable). The U–Th history is simply inherited when galena forms and remains unchanged with passing time.What is the appropriate order of processes for the extraction of lead from Galena? A) Froth flotation B) Calcination C) Roasting D) Self Reduction E) Electrolytic Reduction F) Smelting A C→B→D→E B A→C→D C A→C→E D A→C→F Solution The correct option is B A→C→D Galena (PbS) is a sulphide ore. It is first concentrated by froth flotation process.
