tambang ilmenite hard rock

Ilmenite Wikipedia

Ilmenite is a common accessory mineral found in metamorphic and igneous rocks. It is found in large concentrations in layered intrusions where it forms as part of a cumulate layer within the silicate stratigraphy of the intrusion. Ilmenite generally occurs within the pyroxenitic portion of such intrusions (the 'pyroxene-in' level).

Major Mines & Projects Lac Tio (Havre St-Pierre) Mine

A key factor in the development of the ilmenite reduction process was the need to refine the ore before smelting. In 1954, the Ore Pretreatment Plant was built. The new plant crushed the ore into smaller pieces to remove more gangue, and then roasted it in rotary furnaces to reduce the sulphur content.
