1.0            INTRODUCTION

1.1            Kaolinite

Kaolinite is one of the rare earth compounds that contain high concentration or percent of alumina and silica in the earth crust, and it has the chemical composition Al2Si2O5(OH)4. Rare earth (RE) compounds are “hi-tech” materials used in electronics automotive catalytic converter, glass/ceramic permanent magnets and nuclear energy. High demand/tight supply issues prompt the need for intensive research in the field of rare earth recovery/purification, with emphasis on development of new sources to secure sustainable access to supply in the future. Due to the abundance of Kaolinite in the superficial layers in nature, high specific surface area for adsorption and relatives ease of mining/processing [1].The Kaolinite or rare earths are leached and we can recover high purity and product by solvent extraction. In April 2008, the US Naval medical research institute announced the successful use of a Kaolinite derived aluminosilicate nonoparticles infusion in traditional gauze, known commercially as Quick clot combat Gauze [2]. The purpose of this study is to explain the geochemical principles that govern acid chloride aluminum leaching and to provide a basis for understanding the testing application of acid leaching to the undeveloped resources base [3].
