Seven sections of the book: introduction, primary smelting, hydrometallurgy, electrolytic refining, fire refining, by-product recovery (notably tin, tellurium, zinc and silver), and manufacture of bismuth products, focus on Chinese metallurgical plant operations and include references to common operating difficulties such as difficult-to-melt charges and furnace breakdowns.

Converter-produced blister copper and blast-furnace lead also are treated by fire refining, with both processes depending on the weaker affinity for oxygen of the metals than the impurities they contain. Molten copper in a small reverberatory-type furnace has compressed air blown into it through steel pipes below the surface. This oxidizes zinc, tin, iron, lead, arsenic, antimony, and sulfur ...

The fire-refined copper is then cast into anodes for even further purification by electrolytic refining. Electrolytic refining separates copper from impurities by electrolysis in a solution containing copper sulfate (Cu2SO4) and sulfuric acid (H2SO4). The copper anode is dissolved and deposited at the cathode. As the copper anode dissolves ...
