This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1914 edition. Excerpt: ... two important economic considerations which alone should goad the metallurgist to future discoveries in hydrometallurgical methods: 1. Enhancement of the life and value of a property 50 percent when the hydro-metallurgical process extracts 90 percent, as against 60 percent by the combined concentrating-smelting process, assuming equal cost per pound of metal produced in the two cases. 2. Possible treatment at a profit of certain complex mineral aggregates not otherwise amenable to extraction, recovering the several metals.. Articles not previously accredited: W. L.

Credit is also due to Dr. Edward F. Kern, of the Metallurgical Department of Columbia University, for kindly looking over the manuscript and offering suggestions. n The electrometallurgy of copper is mainly hydrometallurgy, inasmuch as the electric current is used principally for the deposition of copper from its solutions. Up to the present time the application of the current has been confined to the precipitation of copper from solutions originating from metallic copper, in other words to the electrolytic refining of copper, but the application of...
