Title: David Ruff - Innovator in Attapulgite Clay Production

Introduction

David Ruff is an accomplished inventor based in Cockeysville, MD (US). He has made significant contributions to the field of materials science, particularly in the production of attapulgite clay. His innovative methods have led to advancements that improve the performance of this versatile material.

Latest Patents

David Ruff holds a patent for a method of producing purified attapulgite clay, which is also known as Fuller's Earth. This method significantly removes other types of clays and minerals, resulting in enhanced performance. The unique dispersant used in this process fully disperses individual attapulgite particles in water, allowing them to remain in suspension. This dispersant does not fully disperse other clay and mineral species, making it easier to separate them through various techniques. The attapulgite clay can be recovered from the dispersion and dried to produce a finely sized powder from ore, eliminating the need for grinding or milling operations. The dried attapulgite clay, with adsorbed dispersant, can be redispersed in water while retaining thixotropic properties.
