US4206878A Beneficiation of iron ore Google Patents

Iron ore is beneficiated using separation steps based on mineral composition without the use of separation steps based entirely on size. In a preferred sequence of steps the iron ore is passed from a ball mill through a magnetic separator where low iron content tailings are rejected and the concentrate passed to a flotation step, where a high iron content concentrate froth is made and the ...

Dry Iron Ore Beneficiation Iron Ore Separation ST

Iron ore extraction is mainly performed through open pit mining operations, resulting in significant tailings generation. The iron ore production system usually involves three stages: mining, processing and pelletizing activities. Of these, processing ensures that an adequate iron grade and chemistry is achieved prior to the pelletizing stage.

The value of mineralogical analysis for iron ore mining

Oct 08, 2020 Mineralogy of iron ore deposits, directly influencing the outcome of any beneficiation step, must be considered. X-ray diffraction (XRD) is an indispensable tool for fast, accurate and tailored mineralogical analyses. XRD can be used for the quantitative assessment of full mineralogical composition at every step of ore-to-metal process.

Iron ore tailings (IOTs) are a form of solid waste produced during the beneficiation process of iron ore concentrate. In this paper, iron recovery from IOTs was studied at different points during a process involving pre-concentration followed by direct reduction and magnetic separation. Then, slag-tailing concrete composite admixtures were prepared from high-silica residues.
