Extraction of zinc from zinc blende is achieved by

Question

Extraction of zinc from zinc blende is achieved by (A) electrolytic reduction (B) roasting followed by reduction with carbon (C) roasting followed by reduction with anothermetal (D) roasting followed by self reduction

Tardigrade Admin · Accepted Answer

Zinc blende contain ZnS which is first roasted partially and then subjected to reduction with carbon ZnS+O2 arrow ZnO+SO2 Roasting ZnO+C xrightarrowΔ Zn+CO uparrow Carbon reduction

Q. Extraction of zinc from zinc blende is achieved by

electrolytic reduction

roasting followed by reduction with carbon

roasting followed by reduction with anothermetal

roasting followed by self reduction

Zinc blende contain $Z n S$ which is first roasted partially and then subjected to reduction with carbon
$Z n S + O_{2} \to Z n O + S O_{2}$ Roasting
$Z n O + C Δ Z n + CO ↑$ Carbon reduction
