Question

What is the zinc compound obtained by roasting Zinc blende?

Answer 1

Zinc compound obtained by roasting zinc blende:

• Roasting is a metallurgical process that is used to extract pure metal from the ore.
• Roasting is a process by which air is passed through the ore when the concentrated ore is heated. It converts sulphide ore to metal oxide.
• Zinc blende (ZnS) is the mineral sulphide of Zinc.
• The following chemical reaction takes place when Zinc blende is roasted-

$$\begin{gathered} 2\mathrm{ZnS}+3{\mathrm{O}}_2\stackrel{\Delta }{⟶}2\mathrm{ZnO}+2{\mathrm{SO}}_2\uparrow \\ ZincsulphideOxygen\stackrel{\Delta }{⟶}ZincoxideSulphurdioxide \end{gathered}$$

The zinc compound obtained by roasting Zinc blende is Zinc oxide.
