The author presents a practical, technical survey of copper metallurgy, opening with the metal's historical development, uses, and physical and chemical properties before outlining ores and sampling. Preparatory operations such as concentration, briquetting, sintering, and roasting are described, followed by detailed treatments of furnace technologies and operating practice for reverberatory and blast furnaces, charge calculations, and pyritic smelting. The conversion of mattes by Bessemer-style processes is examined, with attention to converter design and flame behavior. Final chapters cover anode preparation, electrolytic refining, casting, and the economic and operational aspects of large-scale practice, supported by illustrations and references.
