are called minerals. Ores are extracted depending on the form of their origin and the degree or concentration and amount of elements in them, and only the stones whose amount and value of the elements in them are reasonable and cost-effective compared to the cost of extraction are extracted with different methods. They are used in various industries. Silicates, sulfides, and oxides are examples of metallic minerals. Also, copper metal, which is a natural metal, is usually not concentrated in the crust. Noble metals such as gold are also extracted from ores.
