Azurite, like malachite, is a copper mineral found in oxidation zones at the roof of ore deposits (the socalled iron gossan), and forms at relatively low temperatures. The orangebrown limonite cover makes the crystals look dull, but underneath the crystals are shiny and .

is limonite metalic mineral. is limonite metalic mineralAlthough originally defined as a single mineral, limonite is now recognized as a mixture of related hydrated iron oxide minerals, among them goethite. is limonite is metallic mineral or not
There are two groups of minerals which are metallic and nonmetallic minerals. Metallic and nonmetallic have to do with a mineral's luster. Minerals such as galena, pyrite, magnetite, and hematite are examples of metallic minerals. Metallic minerals produce the largest amount of luster which makes them very shiny. A nonmetallic mineral is not as reflective.
Limonite is a kind of iron ore. "A concretion is a compact, rounded rock mass formed by localized cementation around a nucleus." "One problem with the hypothesis is that the objects are limonite concretions concerns their hardness... The metallic spheres cannot be scratched with a steel point, indicating they are extremely hard," Cremo continues.
Limonite is scientifically not considered a true mineral as it lacks a definitive chemical formula and crystal structure. However, all mineral reference guides list it together with other minerals. Limonite is a matrix base of many other minerals, and the term gossan is used as a reference to Limonite when it is used as a a matrix...

The streak of a mineral is the color of the powdered mineral. The color may include: white/colorless, green, gray/black, red/orange, gold/brown, blue. Most light colored, nonmetallic minerals have a white or colorless streak, as do most silicates, carbonates, and most transparent minerals.
India's mineral resources are sufficiently rich and varied to provide the country with the necessary base for industrial development. The position is particularly advantageous in metallic minerals of the ferrous group, including the ores of iron, manganese, chromite and titanium.
The most important are: luster, streak, hardness, and cleavage. It is also good to know a bit about such things as specific gravity, fusibility, mineral "habits", and the types of mineral "environments" different minerals are likely to be found in – what types of rock, under what physical conditions.
