Q10 / 90 · JEE Main 2023 (29 Jan Shift 2) · Chemistry

The major component of which of the following ore is sulphide based mineral?

A
Calamine
B
Siderite
Correct answer
C
Sphalerite
D
Malachite

Solution

Calamine, Siderite and Malachite are carbonate containing ores. Sphalerite is a sulphide ore.

Calamine: ${ZnCO}_{3}$

Siderite: ${FeCO}_{3}$

Sphalerite : $ZnS$

Malachite : ${CuCO}_{3} \cdot Cu {(OH)}_{2}$

Hence, the correct answer is option: 'C'.
