Which of the following reaction is/are involved in the extraction of Pb from PbS?

Options

A. `PbS+2PbO to 3Pb+SO_(2)`
B. `PbSO_(4)+2PbS to 2PbO+2SO_(2)`
C. `2PbS+3O_(2) to 2PbO+2SO_(2)`
D. All of these

Answer

D

Explanation

`(a) underset("Self redcution process")(PbS)+2PbO to 3Pb+SO_(2)`
`(a) underset("Self redcution process")(PbSO_(4))+PbS to 2Pb+2SO_(2)`
`(a) underset("Roasting")(2PbS)+3PbO to 2PbO+2SO_(2)`
