In this research, a refractory iron ore is processed, according to the basic facts of mineralogical study. Mineralogy shows that the ore is characterized by the finely disseminated iron minerals with a small amount in the ore. Iron minerals in the ore are mainly hematite and magnetite. On the basis of the ore characteristic, a flowsheet of "stage grinding-low intensity magnetic separation-high ...

Iron Ores | Article about Iron Ores by The Free Dictionary

Magnetite is a common ore of iron. It is found disseminated as an accessory mineral through most igneous rocks. In certain types through magmatic segregation becomes one of the chief constituents, and may thus form large ore bodies. Such bodies are often highly titaniferous.

Magnetite | Mineral Physical - Optical Properties ...

Many ore deposits of economic importance occur in veins. Vein deposits are believed to form when aqueous solutions carrying various elements migrate through fissures in rock and deposit their burden onto the fissure walls. Hot, rising water escaping from cooling igneous plutons may deposit minerals as it ascends through the crust.
