Abstract
A process for producing a clay mineral of chain structure such as sepiolite and attapulgite. The process comprises suspending a metal silicate gel in an aqueous solution which has a pH value of 3-11 at room temperature and contains a clay mineral of chain structure suspending therein, and then heating the resulting suspension at a temperature below 350.degree. C. According to this process, it is possible to produce a clay mineral of chain structure in a simple, stable manner.
