Extractive Metallurgy | Introduction to Chemistry

Metal ores are formed in the process of ore genesis, and they are extracted through mining. Extractive metallurgy is the practice of removing valuable metals from an ore and refining the extracted raw metals into a purer form. Hydrometallurgy uses aqueous solutions to extract metals from ores (leaching).
