3.2 Pyrometallurgy. Pyrometallurgy is a process to make physical and chemical transformations in materials such as metals, minerals, and ores. Pyrometallurgy is also used to produce alloys and compounds or separate metals by density. This process involves high temperatures between 500°C and 2000°C [57 ].

· In this blog post, we’ll discuss how copper is extracted from copper pyrites and what steps are involved in the process. The extraction of copper from copper pyrites involves several steps. First, the ore must be crushed into a fine powder to increase surface area and allow for easier extraction of the metal.
