All ore deposits are mineral deposits, but the reverse is not true. Ore deposit is an economic term, while mineral deposit is a geologic term. Whether a given mineral deposit is also an ore deposit depends on many factors other than the level of concentration and the size of the deposit; all factors that affect the mining, processing, and transporting of the ore must be considered as well.

Mar 19, 2018· Metals form basic oxides e.g., Magnesium oxide(MgO), while non-metals form acidic oxides e.g., . Ag and Cu are best conductors of electricity. Metals and Non-metals can be distinguished on the basis of their physical and chemical properties. Some elements show the properties of both metals and non-metals and are called metalloids.
