Arcelor Mittal operates an iron ore open pit mine and a concentrator near the town of Fermont in Northern Quebec, Canada (Hyma and Meech, 1989). The ore contains from 25% to 35% Fe mostly under the form of hematite. Quartz is the main gangue mineral with less than 3% of other gangue minerals such as mica, ilmenite and garnet. At …
Concentrator. In the processing stage, the mined material is transformed into usable raw material. For iron ore this involves crushing the ore and then concentrating it in different ways, for example by milling, flotation or magnetic separation. At some sites the ore is …

Completed in 1909 (construction started in 1907) on the eastern shore of Trout Lake, just south of Coleraine, MN, the Trout Lake Concentrator served as a custom beneficiation plant for the OIMC's low …
The revamp work will see the construction of a new iron ore concentrator and the necessary infrastructure for transferring the ore feed from the mine to the new …
Apatite is the main source of phosphorous for the making of chemical fertilizers. While apatite is usually recovered from phosphate orebodies as the primary product of a mining exploitation, this paper documents the approach taken to produce a phosphate concentrate as a secondary product from the tailings of a niobium ore …
S. P. GIAMBRA. The 50,000-ton-per-day Concentrator and Crushing Plant, complete with its related water supply, tailings disposal and concentrate handling systems, was started up in a five-month period, with the entire plant obtaining its design capacity six months after the first mill became operational. Individual mill lines, with their spiral ...
We are a leading North American producer and exporter of premium iron ore pellets and high-grade concentrate.
