metallurgy?

Right again.

thank you

Yes, the science of extracting metals from rocky ore is called metallurgy. Metallurgy involves various processes such as mining, crushing, grinding, and separating the ore from the impurities present in it. There are different techniques used in metallurgy, including pyrometallurgy (using high temperatures), hydrometallurgy (using liquids), and electrometallurgy (using electrical currents). These processes aim to extract the desired metal from the ore and transform it into a usable form for various industrial applications.
