The scope of Mining is very limited and can be accessed only if you are truly interested in Mining and are serious about pursuing a career in the same. I suggest you pursue higher education in Mining from an elite foreign university like Colorado School of Mines, Royal School of Mines, and University of New South Wales. This will nurture your technical skills to the best. Another suggestion in this regard is that you can also go for ISM. The enthusiasm for Mining at ISM is like nowhere else.
However, if you are after a good package rather than pursuing your enthusiasm, then IIT KGP is a better option. IIT KGP has an abundance of opportunities for the students academic environment is second to none. It offers extensive exposure and is thus most preferred by Engineering students of all branches.
As far as recruiters are concerned, a large number of them offer jobs to students at IIT KGP mainly because of the credibility of the Institute irrespective of the branch. Also, very few companies offer core jobs in Mining. Therefore, most mining students end up with non-core jobs.
Some Core Companies for Mining visiting IIT KGP are
The average CTC is around 8 LPA.
