Explanation:

In India, the Mineral Conservation and Development Rules (MCDR) and the Indian Bureau of Mines (IBM) categorize minerals into major and minor minerals.

Bentonite - This is a minor mineral in India. Bentonite is used in a variety of industrial applications such as drilling mud, and as a binder in foundry sand, but it is not officially designated as a major mineral.
Chromite - This is a major mineral in India. Chromite is the main source of chromium, which is important in steel production and several industrial applications. India has significant chromite deposits, especially in Odisha and other regions, and it is considered a major mineral.
Kyanite - This is a minor mineral in India. Kyanite is used as a refractory material and in the production of ceramics but is not classified as a major mineral.
Sillimanite - Like Kyanite, Sillimanite is also classified as a minor mineral in India. It is used in the manufacturing of refractories and ceramics but is not considered a major mineral.
