Question

The sulphide ore of zinc is \(X\) and carbonate ore of zinc is \(Y\). \(X\) and \(Y\) are respectively

• A. Kaolinite, siderite
• B. Siderite, calamine
• C. Calamine, sphalerite
• D. Sphalerite, calamine

Hint:

Important ores of zinc: \[ \boxed{ \begin{aligned} &\text{Sphalerite} &&\rightarrow \mathrm{ZnS}, &\text{Calamine} &&\rightarrow \mathrm{ZnCO_3}, &\text{Zincite} &&\rightarrow \mathrm{ZnO}. \end{aligned} } \]

Answer 1

The Correct Option is D

Step 1: Recall the important ores of zinc. The important sulphide ore of zinc is \[ \boxed{\text{Sphalerite }(\mathrm{ZnS}).} \] The important carbonate ore of zinc is \[ \boxed{\text{Calamine }(\mathrm{ZnCO_3}).} \]

Step 2: Match the ores. Thus, \[ X=\text{Sphalerite} \] and \[ Y=\text{Calamine}. \]

Step 3: Choose the correct option. Hence, \[ \boxed{X=\text{Sphalerite},\qquad Y=\text{Calamine}.} \] Therefore, the correct option is \(\boxed{(D)}\).
