metallic ores occur in every kind of rock and some varieties of soil. the metallic minerals are concentrated into rich masses by igneous, hydrothermal, or erosionalweathering processes. metals such as chromium, platinum, nickel, copper, and iron can precipitate as sulfide minerals
apr 16, 2019 mineral is a solid, naturally occurring combination of inorganic substances. metallic minerals are minerals which contain one or more metallic elements. metallic minerals occur in rare, naturally formed concentrations known as mineral deposits.
some metals are held inside rocks as minerals. the rock or mineral that holds the metal is called an ore. An ore is heated with chemicals until it melts and the pure metal separates out as a liquid. the liquid then cools and hardens. few metals, such as gold, silver, and copper can be found in
nov 18, 2015 metallic minerals usually originate from igneous rocks. An igneous rock is a type of rock that is formed by the cooling and solidification of magma or lava. magma is made by melting existing rocks under very high temperature and low pressure.
source for metallic minerals. the primary properties of metallic minerals are metal. most of these minerals can be found on the earths crust. igneous and metamorphic rocks are mostly holding these metallic minerals. most metallic elements originate in the center of the earth and they come on the surface with lava or magma.
