Mode of Occurrence of Minerals Minerals are generally found in ores, which is actually an accumulation of any mineral mixed with other elements. To obtain a pure mineral, the it has to be separated from its ore. This process of separating the mineral from its ore is called smelting Smelting of iron ore Minerals generally occur in many forms, they are: 1.
meteoric iron when a piece is polished, etched, and examined by the optical microscope, it is known as telluric iron,, terrestrial iron. The major occurrence of telluric iron is in association with the basalts of Western Greenland. Large boulders are on exhibit at the Natural History Museums in Stockholm, Copenhagen, and Helsinki.
Mining of Iron Ores. satyendra; March 14, 2014; 0 Comments ; Hematite, Iron ore, mines, mining, Mining of Iron Ores. Iron ore is a type of mineral and rock from which metallic iron is extracted economically. This ore is normally rich in iron oxides and vary in color from dark grey, bright yellow and deep purple to rusty red.
Mining of iron ore is partly or fully influenced by one or combination of several factors among them being topography, geology and geologic structure, hydrogeological conditions as well as soil and general ground stability. The implications of the aforementioned factors to the whole mining process [3]
The ore grade, or concentration of an ore mineral or metal, as well as its form of occurrence, will directly affect the costs associated with mining the ore. The cost of extraction must thus be weighed against the metal value contained in the rock to determine what ore can be processed and what ore is of too low a grade to be worth mining.

The process mineralogy study carried out by the authors determined ore mineralogy and ascertained occurrence of Nb and Ta and their mineral ...
Occurrence, uses, and properties. Iron makes up 5 percent of Earth''s crust and is second in abundance to aluminum among the metals and fourth in abundance behind oxygen, silicon, and aluminum among the, which is the chief constituent of Earth''s core, is the most abundant element in Earth as a whole (about 35 percent) and is relatively plentiful in the Sun and other stars.
Lownickel iron (up to percent nickel) is called kamacite, and highnickel iron (up to 50 percent nickel) is called taenite. Both crystallize in the cubic system. A third form of ironnickel, mainly found in meteorites and crystallizing in the tetragonal system, is called tetrataenite.
