Chemical analysis facilities are available at the laboratories established at the head office and the regional offices. Conventional and trace element analysis is being carried out successfully at the laboratories that have led to, assess the grade of various mineral deposits and established several mineral based industries, in the State. Success of a few international collaborative projects and in-house projects are to the credit of the laboratories.
