Rocks and minerals are important materials that make up the earth and are also valuable resources for people's production and life.

Mineral resources belong to the state and no organization or individual may exploit them privately.
my country has discovered 171 kinds of minerals and is one of the few countries in the world with a relatively complete range of minerals. Among them, the proven reserves of more than 20 minerals, including rare metal ores, tungsten ores, and tin ores, rank among the best in the world.
