Particle Size Distribution Study of China Clay Deposits of Nagaur Area, Rajasthan, India

Subhash Chandra Janagal | M. S. Shekhawat

Abstract: Two prominent deposits of china clay are occurring in Nagaur area, Rajasthan. These deposits occur as horizontal sub-surface beds of variable thickness. The deposits occur in association with recent to sub-recent sediments of the Marwar Supergroup. The china clay produced from the area is greyish-white to creamish-white in colour and poor in silica. The deposits are being developed and utilized by open-cast, semi-mechanized methods of mining. Nearly 50% china clay produced from the area is found suitable for its use in ceramic industry. This study is focused on particle size distribution analysis of four china clay samples using laser diffraction technique. The analytical data suggest that out of four samples of china clay, two have moderately good plasticity and rest of two shows poor plasticity.
