Ancient Metallurgy - University of California, San Diego

Metallurgy is the process of working metal into artifacts (tools and toys). Although small amounts of metals are found in relatively pure form, most must be extracted from more complex ores by removing the "impurities" (non-metal or other metal) from the combination ore.

Metallurgic Processes | Boundless 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 ).
