Which of the following steps is correctly related to different steps inovled in the extraction of Zn from Zinc blende?
- Gravity method \(\text { → }\) Froth Floatation \(\text { → }\) Roasting at 900 - 1000oC \(\text { → }\) Reduced with coke \(\text { → }\) Electrolytic refining
- Roasting at 100o C \(\text { → }\) Leached with H2SO4 \(\text { → }\) Treatement with milk of lime \(\text { → }\) Acidified & Electrolysed
- Both (a and b)
- None of these.
Answer
(A) Gravity method → Froth Floatation → Roasting at 900 - 1000 o C → Reduced with coke → Electrolytic refining
