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

Answer 1

Answer: (B)

roasting followed by reduction with carbon

Answer 2

The correct answer is Option is B) roasting followed by reduction with carbon

Zinc blende contains ZnS which is first roasted partially and then subjected to reduction with carbon
$ZnS+O_2 \rightarrow ZnO+SO_2 Roasting$
$ZnO+C \xrightarrow{\Delta} Zn+CO \uparrow Carbon reduction$
