• Description:
  This study compares six nonbauxitic alumina processes with the objective of selecting the two most promising candidate processes for further study. The comparisons cover both technical and economic aspects of alumina process plants of commercial size in the United States. The processes considered were hydrochloric acid-clay (evaporative and gas-induced crystallization), nitric acid-clay, sulfurous acid-clay, anorthosite-lime sinter, and alunite. 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 from which conclusions can be drawn for selecting the two most promising processes. This is the first study of a three-part program.
