Consider the following statements with respect to the Coking Coal and the Lignite Coal:
1. While Coking Coal is primarily used for metallurgical purpose, Lignite coal is primarily used in power generation
2. Lignite coal comprises lion’s share of Indian coal
Which among the above statements is / are correct?
Prime Coking – Mainly used for metallurgical purpose.
Medium Coking – Mainly used in steel industry.
Semi Coking – Mainly in cement, fertilizer and sponge iron industries.
Non Coking Coal: Non- coking coal comprises lion’s share of Indian coal. Based on Useful Heat Value (UHV), it is classified into grades A to G for commercial use.
