National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Alumina Process Feasibility Study and Preliminary Pilot Plant Design. Task 2 Report: Comparison of Two Processes.

PB286639

Publication Date	1978
Personal Author	Bengtson, K. B.; Chuberka, P.; Malm, L. E.; McLaughlin, A. E.; Nunn, R. F.
Page Count	159
Abstract	This study 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 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.
