Most non -metallic minerals are used for industrial process especially as raw materials. These materials are poor conductors and cannot be used as one. They cannon be used for wiring because they lack metallic bonds within their lattices. So, the best used is for industrial processes, for the valuable ones, they are of good gem grade.
The non-metallic minerals are very poor conductors of both heat and electricity. The non-metallic minerals have a low melting point as well as a low boiling point. The non-metallic minerals can easily gain electrons. The non-metallic minerals don't have any metallic components.
