Abstract
The Bureau of Mines has developed a technically feasible continuous single-stage leaching and thickening system for extracting manganese from umber by a sulfuric acid-ferrous sulfate process; the cocurrent leaching and thickening system proved simpler to operate and control than the countercurrent leaching and thickening system developed earlier. Related tests investigated the use of a centrifuge to replace thickeners for separating the product liquor from ore residues and compared several chemical agents for removing iron from the pregnant manganese leach solutions. Results of some exploratory autoclaving tests are also given. Work done in cooperation with the University of Alabama.
