If you are a student in metallurgical engineering, a process chemist, or just a curious mind wondering how we turn rocks into bridges and smartphones, you have likely heard one name whispered in lecture halls: Terkel Rosenqvist .

Ask your professor if the department has a PDF license. Many departments bought digital access for remote learning during COVID. You might already have legal access without knowing it.

Happy smelting (safely, and legally)! Do you own a copy of Rosenqvist? Drop a comment below about your favorite chapter—mine is the one on matte smelting thermodynamics!

But if you want to actually learn extractive metallurgy—to truly understand slag/metal reactions and roasting equilibria—buy a used physical copy or borrow it from a library. This is a book you work through with a pencil, not just a file you skim on your phone.
