While hydrometallurgy involves using water for the extraction of metals, pyrometallurgy is a heat-based extraction and purification process. As with the water-based process, pyrometallurgy generally involves three steps: Roasting: This refers to the heating of compounds in air and transforming sulfide ores into oxides, creating gas.

Pyrometallurgy is an extractive metallurgy field that uses high-temperature techniques to extract and purify metals, alloys, or mattes from primary ores and/or secondary resources. Because operating temperatures frequently near 1500°C, pyrometallurgical processes are difficult, high-risk, and energy-intensive.
