Abstract

"The United States Bureau of Mines Experimental Station at Rolla has recently been conducting an intensive investigation of the amenability of Arkansas red ores to enrichment by standard ore dressing methods. These Arkansas ores are low grade with the estimated reserves running into several million tons. They can be concentrated to meet all Grade B ferromanganese specifications - with the exception of that of the phosphorus content, but in all cases the phosphorus is so high as to make the ore worthless under present conditions. This condition suggested the problem of trying to discover a method by which the phosphorus could be eliminated, which in turn called for a positive identification of the phosphorus-bearing compounds. The thesis as finally adopted chose the following lines of pursuit: 1. A study of standard known manganese and phosphorus minerals was to be made in order to become familiar with their properties. 2. The data obtained from this study was to be applied to the study of actual manganese ores, especially those from the Batesville District in Arkansas. 3. On the completion of the identification work, if the chemical composition and interlocking of the phosphorus-containing mineral would permit either a mechanical or chemical separation from the manganese minerals, the development of a practical method of eliminating the phosphorus would be undertaken"--Introduction, page 5.
