Composition of siderite ore is
Show Hint
Ore composition knowledge is necessary for common extraction problems. Important ores to remember include:
- Hematite ($\text{Fe}_2\text{O}_3$), Magnetite ($\text{Fe}_3\text{O}_4$), Siderite ($\text{FeCO}_3$).
- Zinc Blende ($\text{ZnS}$), Calamine ($\text{ZnCO}_3$), Smithsonite ($\text{ZnCO}_3$).
- Bauxite ($\text{Al}_2\text{O}_3 \cdot 2\text{H}_2\text{O}$).

The Correct Option is A
Solution and Explanation
Step 1: Define Siderite.
Siderite is a mineral composed primarily of iron(II) carbonate.
Its chemical formula is $\text{FeCO}_3$.
Step 2: Identify the given options.
(A) $\text{FeCO}_3$: Iron(II) carbonate. This is Siderite.
(B) $\text{ZnCO}_3$: Zinc carbonate. This is Smithsonite (or Zinc spar).
(C) $\text{CuCO}_3 \cdot \text{Cu}(\text{OH})_2$: Copper(II) carbonate hydroxide. This is Malachite.
(D) $\text{CuFeS}_2$: Copper iron sulfide. This is Chalcopyrite (a major copper ore).
Step 3: Conclude the correct option.
The composition of siderite ore is $\text{FeCO}_3$.
