ACIDIC DISSOLUTION OF MAGNETITE: EXPERIMENTAL

Magnetite (Fe 3 O 4) is a key economically valuable component in iron ore and is extracted by dissolution processes, but among the Fe (oxyhydr)oxides its solubility behavior is one of the least understood.The objective of this study was to improve understanding of magnetite dissolution mechanisms leading to thermodynamic equilibrium by comparing the dissolution of two solid samples, one ...

Mineral chemistry of magnetite from magnetite-apatite ...

Magnetite-apatite deposits, sometimes referred to as Kiruna-type deposits, are major producers of iron ore that dominantly consist of the mineral magnetite (nominally [Fe²⁺Fe³⁺₂]O₄). It remains unclear whether magnetite-apatite deposits are of hydrothermal or magmatic origin, or a combination of those two processes, and this has been a subject of debate for over a century.

Which of the following ore is best concentrated by class ...

- Option (C) Magnetite is a rock mineral which is having a chemical formula of \[F{e_3}{O_4}\]. On seeing the chemical formula, we can say that there is no sulphide group present in the Magnetite. Therefore, it cannot be concentrated by the froth flotation method. Magnetite is an incorrect answer.

Which method is generally used for the concentration of ...

Froth floatation is used for the concentration of sulphide ores. Hydraulic washing is used for the concentration of lead and tin ores. Leaching is used for the concentration of aluminium ores. Magnetic separation is used for the concentration of iron ore, magnetite ore, non- magnetic ore of tin, etc.
