Most raw materials are elements, for example, metals, but also certain chemical compounds that are used industrially. Many have very typical deposits, others occur in several deposit forms. But the mined raw material always characterizes the mine, one speaks of gold mine or of colliery, of salt mine or tin mine. For each raw material, we have tried to briefly present the characteristics of the material, its deposits and the special features of mining. Of course, this must remain brief, but if you are interested in more details, please refer to the geologic literature.
