Both gold and silver are metallic elements, they are transition metals to be more precise.
Cebu has deposits of both metallic and non-metallic minerals. Among the metallic mineral deposits in Cebu are gold, copper, silver, and other non-ferrous metals. Among Cebu's non-metallic resources are dolomite, silica, red clay, phosphate and guano.
Non metallic minerals are minerals that have no shine and crumble easily. Non-metallic minerals are sand, gravel, and stone.
fossils are not metallic minerals. marbles are non metallic minerals.
This is not true. The only metallic minerals that are at all common are native gold, silver, copper, and platinum. Gold and silver have Mohs hardness of 2.5, copper 3.0, and platinum 4 to 4.5. That's rather soft. By contrast, non-metallic minerals include quartz, topaz, corundum, and diamond, with Mohs hardness 7, 8, 9, and 10 respectively.

The two basic groups of metallic mineral resources are ferrous minerals, which contain iron, and non-ferrous minerals, which do not contain iron. Ferrous minerals include iron ore, while non-ferrous minerals include copper, lead, zinc, gold, and silver.
Metallic minerals are composed primarily of metallic elements and have a metallic luster and other properties, such as the ability to conduct electricity. Non-metallic minerals do not have these characteristics.
Non metallic minerals include quartz, mica, calcite, and feldspar. Metallic minerals include pyrite, hematite, magnetite, galena, chalcopyrite, iron, and copper.
Examples of metals: sodium, uranium, Mercury, zinc, plutonium, calcium etc. Examples of nonmetals: oxygen, helium, carbon, sulfur, argon, nitrogen etc.
what are countries that hve metalic non metallic minerals
Metallic minerals have a significant metallic elemental composition, resulting in a set of physical properties that are specific to them such as conductivity and metallic luster. Non-metallic minerals do not possess significant elemental metallic composition of exhibit those physical properties.
