Magnetite an overview ScienceDirect Topics

Magnetite, ideal formula Fe 3 O 4, is an intriguing mineral, and not only because it is magnetic.The formula could be written as Fe 2+ Fe 3+ 2O 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.get price

Improving reverse flotation of magnetite ore using pulse

An improved performance was achieved using a pulse magnetic field during the reverse flotation of magnetite ore in a flotation column.
