    Magnetite - an overview | ScienceDirect Topics

    Magnetite, ideal formula Fe 3 O 4, is an intriguing mineral not only because it is magnetic.The formula could be written as Fe 2 +Fe 3 +2 O 4, which more precisely designates one of its peculiarities.It contains both ferrous (Fe 2 +) and ferric (Fe 3 +) ions, implying synthesis, growth, and stability within an environment where oxidized and reduced states of iron are present and maintained.

    Effect of additives on grinding of magnetite ore

    Aug 01, 1991 These investigations established that an addition of 200 g of CaO per metric ton of ore was the most effective in grinding quartz preferentially over magnetite at 75% solids concentration by weight. The limited rheological studies conducted suggest that the effect could either be due to dispersion or the structural modification of quartz.
