Ebook Pyrite Smelting

This volume is a reprint of the discussion on Pyrite Smelting which ran through various issues of The Engi neering and Mining Journal between October, 1903, and February, 1905. The contributions have been revised by the respective authors, and the editorial comment ap pearing at intervals in the Journal has been modified into the introductory remarks, which now precede the suc cession of letters contributed by no less than twenty metallurgists; Emphasis was placed upon the value of the discussion, and a notable addition was given to the permanent usefulness of it, by a review prepared by Dr. Edward D. Peters, the professor of metallurgy at Har vard University. Earlier, in 1903, a discussion arose consequent upon an article dealing with the relation between hearth-area and furnace capacity; this article and the criticism which it elicited are also published in this volume, together with three other papers germane to the subject.
