"Sulphur is a mineral material which is as basic as steel to our industry and economy. This fact is not generally realized because it is seldom seen, but it goes into the manufacture of practically every article of clothing we wear, and the food we eat is dependent upon it. Most items we produce require the use of sulphur at some stage of their manufacture. The consumption of sulphur has been increasing rapidly and is now far above its World War II peak. Production has been greatly increased but has been unable to keep up with the increasing demand. This situation is extremely critical because the world reserves of natural sulphur are being rapidly depleted....

Many other sources of sulphur are now being investigated to provide supplements to the present production. Iron sulphides in the form of pyrite, pyrrhotite, and marcasite have been used as a source of sulphuric acid, and are now receiving more attention in the United States and Canada. Low grade elemental sulphur deposits in the western U.S. and in South America have been studied and a recovery method devised, so these promise to provide an important additional supply of brimstone. The author of this paper has investigated the possibilities of the Upper Mississippi Valley zinc and lead district as a potential producing region of iron sulphide concentrates which might be used in production of sulphur compounds to acid in satisfying the demands of the surrounding industrial area "--Introduction, pages 1, 5.
