5203 |a"Based on a review of the extensive published literature on the recovery of alumina from clays and shale, sufficient experimental work was done on a bench scale to establish a flow sheet whereby these materials might he treated for the recovery of cell-grade alumina. The significant step in the processing is the recovery of potassium alum, and its purification by either recrystallization or liquid-liquid extraction."
