Metals from rocks. Some metals are held inside rocks as minerals. The rock or mineral that holds the metal is called an ore. An ore is heated with chemicals until it melts and the pure metal separates out as a liquid. The liquid then cools and hardens. A few metals, such as gold, silver, and copper can be found in pure form as metal elements.

Extraction of Resources | Geology
Mining is the extraction of valuable minerals or other geological materials from the earth from an orebody, lode, vein, seam, or reef, which forms the mineralized package of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, dimension stone, rock salt, potash, gravel, and clay.

Extraction of ores and minerals introduction: Mineral resources exploitation refers to solid metal and nonmetal ore deposit mining, including the surface outcrop ore bodies and the strip mining of the ore bodies and shallow deep blind ore, the underground mining of the ore bodies. ...
The Geology of Rare Earth Elements
Unlike metal sulfides, which are chemically simple compounds, REEbearing minerals are quite complex. Base metal sulfide ores, such as sphalerite (ZnS), are typically smelted to burn off sulfur and separate impurities from the molten metal. The resulting metal is further refined to near purity by electrolysis.
