Abstract
As part of the Bureau of Mines program to broaden utilization of abundant low-quality mineral materials, the Tuscaloosa Metallurgy Research Laboratory conducted beneficiation studies on two Alabama clays. The main purpose of these studies was to develop improved plasticity and green strength in both clays and compare these improved properties with those of a typical ball clay. Whiteness of the clays was also considered. The results indicated that by adjusting the ph of the kaolin to approximately 9, a substitute for ball clay could be obtained. The investigation also showed that by a combination of attrition grinding and sodium dithionite leaching to remove iron, the underclay could be upgraded to a ball clay material. Work done in cooperation with the University of Alabama.
