This is a magnetite mine that will supply 22 Mta iron ore in the first phase of development [3]. The investment costs amounted to 3.3 to 3.5 bill. US$. In the beneficiation plant, high-pressure grinding rolls (HPGR) with downstream dry screening and dry magnetic separation are used as tertiary crushers to obtain a concentrate with 67 % iron22.4: Beneficiation. Beneficiation is any process which removes the gangue minerals from ore to produce a higher grade product, and a waste stream. Beneficiation may involve physical or chemical processes. Often, as in the case of panning for gold, the desired ore or metal is denser than the gangue.22.4: Beneficiation Chemistry LibreTexts

Abstract. Flotation is the most effective solution, both technologically and economically, when upgrading iron concentrates. Research regarding iron ore flotation began in 1931, demonstrating thatThe taconite ore processing industry produces usable concentrations of iron-bearing material by removing nonferrous rock (gangue) from low-grade ore. The six-digit Source Classification Code (SCC) for taconite ore processing is 3-03-023. Table 11.23-1 lists the SCCs for taconite ore processing.

Commercialization of Taconite MNopedia
Though taconite was identified as an iron-bearing rock on the Iron Ranges of northern Minnesota long before the 1950s, it wasn’t until then that it was extracted, processed, and shipped to steel mills on the Great Lakes. As natural ore reserves diminished, taconite became an alternative source of iron that allowed the Iron Range to Beneficiation of Iron Ore and the treatment of magnetic iron taconites, stage grinding and wet magnetic separation is standard practice.This also applies to iron ores of the non-magnetic type which Beneficiation of Iron Ore 911 Metallurgist
