Introduction
The ancient history of mineral processing in the Indian sub-continent is a fascinating subject. But its pursuit is hazardous for any serious scholar on account of several reasons. The archaeologically discovered artifacts are often finished products, and considerable intelligent guessing is necessary even to hypothesis what raw material and what technology might have been used to produce such metallic and nonmetallic artifacts . Ancient literature's on mineral processing and metallurgy in India are scanty, and great care must be taken to reconstruct the glory of ancient Indian technology.
