Siderite is

Options

A. `Fe_(2)O_(3)`
B. `FeCO_(3)`
C. `SnO_(2)`
D. `ZnC`

Explanation

**Step-by-Step Text Solution:**

1. **Understanding Siderite**: Siderite is a mineral that is primarily composed of iron carbonate. It is important to identify its chemical composition to understand its properties and uses.

2. **Chemical Formula**: The chemical formula for siderite is FeCO₃. This indicates that each unit of siderite contains one iron (Fe) atom, one carbon (C) atom, and three oxygen (O) atoms.

3. **Naming**: The name "siderite" comes from the Greek word "sideros," which means iron, reflecting the mineral's iron content.

4. **Classification**: Siderite is classified as a carbonate mineral, which means it contains the carbonate ion (CO₃) in its structure.

5. **Occurrence**: Siderite is often found in sedimentary rocks and can form in various geological environments, including hydrothermal veins and sedimentary deposits.

6. **Uses**: Siderite is primarily used as an iron ore and can be processed to extract iron for various industrial applications.
