Can ores be non metallic?

The mineralogy of the ores is characterized by native gold, chalcopyrite, pyrite and magnetite as the main metallic minerals, and garnet, diopside, quartz and calcite as the major nonmetallic minerals.

Bornite, molybdenite, specularite and chlorite, phlogopite are also common (Fig.


What are non metallic mineral resources?

Definition: Non-metallic mineral reserves consist of stone quarries and clay and sand pits; chemical and fertiliser mineral deposits; salt deposits; deposits of quartz, gypsum, natural gem stones, asphalt and bitumen, peat and other non-metallic minerals other than coal and petroleum.

Is Rock Salt metallic or nonmetallic?

The nonmetallic minerals (carbon, diamond, coals, bitumen, asphalt, boron, sulfur, rock salt, etc.) lack the properties of the metallic minerals such as a bright metallic luster, hardness, density, and good conduction of heat and electricity.

What are two non metallic minerals?

Nonmetallic minerals are, for example, sand, gravel, limestone, clay, and marble. Such materials lack metallic characteristics like good electric and thermic conductivity, luster, rigor, and malleability; they are, however, essential for many industries.
