Abstract
This report provides the process technology, preliminary design, capital, and operating costs for a 25-ton-per-day pilot plant to produce cell-grade alumina using a clay-hydrochloric acid extraction- hcl gas induced crystallization process. The process was selected by the Bureau of Mines as the more promising method to produce cell- grade alumina from clay based on the results of two previous reports. The pilot plant process utilizes a unique dual crystallization process to produce aluminum-chloride-hexahydrate crystals with sufficient purity when decomposed to meet stringent alumina product specifications. The size of the pilot plant was selected to permit scaleup to commercial size plants of equipment, technical, and economic parameters.
