The role of calcination in metallurgical operations is:
(d) to decompose carbonates and drive off moisture and organic matter
- Strong heating of ore in the absence of air is known as calcination
- Usually, carbonates are converted into oxides by this method
- the moisture is removed by this method as in the case of iron ore
- Apart from this, organic matter is also removed by this method
- So the correct answer is option (d)
