Optical Physical Properties Of Iron Ore

26-04-2018· Most of the iron ore mined today is a banded sedimentary rock known as taconite that contains a mixture of magnetite, hematite, and chert. Once considered a waste material, taconite became an important ore after higher grade deposits were depleted. Today’s commercial taconites contain 25 to 30% iron by weight.

Etymology. The word garnet comes from the 14th‑century Middle English word gernet, meaning 'dark red'.It is borrowed from Old French grenate from Latin granatus, from granum ('grain, seed'). This is possibly a reference to mela granatum or even pomum granatum ('pomegranate', Punica granatum), a plant whose fruits contain abundant and vivid red seed covers (), which are similar in shape, size ...

12-01-2020· History . Iron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores.   The carbon within the wood would have reacted with the oxygen in the ore, leaving behind a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present-day Iraq) between 2700 and 3000 BCE.

Optical Properties of Minerals: Such properties of a mineral which are related to the behaviour of light while being transmitted through or reflected from it are grouped under optical properties. They are of great significance in the determinative mineralogy and highly useful in identifying individual minerals occurring in very small, physically inconspicuous grain size, as for examples in rocks.
