extraction of metals methods of extraction of metalsthe process of extracting metal ores buried deep underground is called mining. the metal ores are found in the earths crust in varying abundance. the extraction of metals from ores is what allows us to use the minerals in the ground! the ores are very different from the finished metals that we see inlife cycle of a mine natural resource developmentonce removed, the ore is transported for processing using large haul trucks. milling. regardless of the deposit type and mining process, ore must be separated from the waste rock once it has been removed from the ground. the minerals are removed from the ore by using one orextraction and processing of minerals theaug , · there are various ways to extract and process minerals. discover the process of extracting minerals from the earth, the two main methods, and the environmental impact of mineral extraction.
