Used copies of the English translation (often published by McGraw-Hill or Tapir Academic Press) can be found on specialized second-hand textbook marketplaces. 7. Modern Relevance and Sustainable Metallurgy
An intensive thermal process where the ore is melted, separating into a dense, metallic or matte phase and a lighter, molten silicate waste phase called slag.
High-temperature reactions often involve multiple phases (e.g., solid ore reacting with a gas, or liquid metal reacting with a liquid slag). Rosenqvist highlights that chemical reaction rates at interfaces are typically very fast at high temperatures; consequently, the overall rate-limiting step is usually the transport (diffusion) of reactants or products through boundary layers. Heterogeneous Reactions
Dissolving metals from ore using chemicals (e.g., acid leaching of copper ores). Purification: Removing impurities from the leachate. principles of extractive metallurgy terkel rosenqvist pdf
: Analysis of the behavior of liquid metals and slags.
Using an impure metal anode that dissolves in an electrolyte under an electric current, depositing a highly pure layer of metal onto the cathode (crucial for copper and gold production). The Contribution of Terkel Rosenqvist
As the steel industry shifts away from coal-fired blast furnaces toward Hydrogen Direct Reduced Iron (H-DRI), engineers use Rosenqvist’s thermodynamic principles to calculate the heat balances and kinetic constraints of reducing iron oxides with H2cap H sub 2 gas instead of COcap C cap O Used copies of the English translation (often published
: Blowing oxygen through molten metal to selectively oxidize impurities, which then float into a slag layer.
Looking for more resources? Pair Rosenqvist’s work with “The Making, Shaping, and Treating of Steel” (for ferrous metals) and “Extractive Metallurgy of Copper” by Davenport et al. (for non-ferrous). Together, they form a complete education in modern metal extraction.
The book's influence extends significantly into professional practice. Working metallurgists often keep a copy on their shelves, finding it an indispensable resource for its "great sections on slag" and its comprehensive coverage of fundamental principles that underpin daily problem-solving in smelters and refineries. High-temperature reactions often involve multiple phases (e
: Thermal decomposition of a solid without melting. An example is heating limestone to produce lime:
Electrometallurgy uses electrical energy to drive the reduction of metal ions. This is critical for highly reactive metals (such as aluminum, magnesium, and sodium) that cannot be reduced by carbon or carbon monoxide. Aqueous Electrowinning
A significant portion of the book focuses on the structure and thermodynamics of (silicate melts) and mattes (sulfide melts), which are crucial for separating the desired metal from impurities.
