Chemistry - Metallurgy Question with Solution | TestHub
A metal (M) is extracted from its sulphide ore (X) by using following steps :
After sedimentation, ore is agitated by compressed air in the mixture of water and pine oil. Concentrated ore is burnt with excess of oxygen gives resulting product (p). (p) is either smelted with anthracite to produce metal or (p) is treated with dil. H2SO4 to dissolve (p) and filtered solution is electrolized for the deposition of metal. Which of the following steps is/are involved in the metallurgy of metal (M) from metal sulphide(X).
Options:(select one or more)
Answer:
Solution:
The ore (X) is concentrated by Froth Flotation. Roasting converts sulphide ore to oxide (p). (p) can be reduced to metal (M) by carbon reduction (smelting with anthracite) or by leaching with H₂SO₄ followed by electrolytic reduction. Thus, both B and C are correct pathways.
