Copy of "The Concentration of Iron-Ore", a pamphlet by John Birkinbine and Thomas Edison, published 1889 by the American Institute of Mining Engineers. An extremely rare piece, this copy also includes a flyer for Birkinbine's engineering offices at rear and the office's embossed seal on the first page. Birkinbine and Edison worked alongside each other at the Edison Ore-Milling company, a failed venture by Edison that attempted to separate iron from sand and ground rocks using a large electromagnet. The pamphlet describes this process in detail with text, charts, and diagrams.
The pamphlet is mostly split along the spine with one chip on the rear cover, as well as some tearing at one corner. Pages are all in excellent condition; very minimal toning with no other discoloration on pages or cover. See photos. Approx. 6"x9".
