The report contains the results of the additional data obtained with particular reference to the economic feasibility of recovering sulfur and iron from pyrites removed from coal. It discusses the beneficiation processes required to obtain the proper grade of pyrite; the methods of treating pyrite to obtain sulfur (in the form of sulfuric acid) and the processing of the iron calcines to obtain suitable grades of iron oxide.
