Abstract

"The object of this investigation was to study some of the Southeast Missouri lead ores and tailings to trace the freeing of galena through all of the screen sizes. It was also desired to determine the efficiency of recovery with the present treatment and, whether or not a change to finer crushing would be advisable. In order to isolate parts of different specific gravity in the ores and tailings, heavy liquids were used" – Object of Investigation, p. 2.
