Processes for producing a blended bleaching clay product and blended bleaching clay products produced by those processes

摘要

A process for the production of a bleaching clay product which includes the steps of selecting a naturally occurring, acidic hormite clay product, cleaning and crushing the hormite clay products to form clay clumps, selecting a naturally occurring less acidic, clay product which contains a higher level of montmorillonite than does the acidic hormite clay, aging the crushed hormite clay for about one (1) month or more, blending the aged hormite clay with the less acidic clay product either before or after aging and activating the clay with small quantities of acid. An acceptable bleaching clay product can be produced without activation with acid.
