Pyrometallurgical processes involve the extraction and purification of metals from their ores using high temperatures. This method typically includes steps like roasting, smelting, and refining, where heat is applied to separate valuable metals from impurities. Commonly used for metals like copper, zinc, and lead, pyrometallurgy is essential in the mining and metallurgical industries. The primary advantage of pyrometallurgy is its ability to handle large quantities of ore efficiently. However, it can also produce significant emissions and waste, leading to environmental concerns. Innovations in technology aim to reduce these impacts while improving the efficiency of metal recovery.
