Question

Quizplus · Accepted Answer

Pyrometallurgy involves using heat to extract and refine metal from ores. This method is used for high melting point metals such as iron, copper, and lead. Aqueous solutions and reduction reactions may be used in other metallurgical processes, but they are not specific to pyrometallurgy. Forming metal parts using heat and small crystals of metal is a process called casting, which is not the same as pyrometallurgy. Forming metal parts using electricity is called electroforming, which is also not the same as pyrometallurgy.
