• Description:
  This study, the second of a three-part program, compares two nonbauxitic alumina processes with the objective of recommending the single most promising method for producing cell-grade alumina. The comparisons cover both technical and economic aspects of alumina process plants of a commercial size in the United States. The two processes (nitric acid-clay and hydrochloric acid-clay using hcl gas- induced crystallization) considered in this study were selected by the Bureau of Mines on the basis of factors reported in a previously issued task 1 study comparing six nonbauxitic alumina processes. Technical appraisals for each process complete with process descriptions, heat and material balances, flowsheets, and equipment lists have been prepared based on published information available through the Bureau of Mines miniplant program and other nonproprietary sources. Technical and economic comparisons are made which show that the hydrochloric acid-clay process is the more promising method to produce cell-grade alumina from nonbauxitic sources.
