In this paper, suspension magnetization roasting and magnetic separation technology were utilized to recover iron tailings. The results showed that iron Dry Benefication Of Low-Grade Iron Ore Fines Using a ,Iron ore extraction is mainly performed through open pit mining operations, resulting in significant tailings generation [2]. 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.

CA2859035A1 Separation of iron from value metals in
The invention provides a process for the leaching of a laterite ore, concentrate, tailings or waste rock for the recovery of value metals, at least one value metal being nickel. The laterite ore or concentrate is subjected to a leaching step with a lixiviant comprising hydrochloric acid to leach nickel from the laterite ore, followed by a liquid/solids separation step.Extraction of Iron from Hematite Xinhai,2020-4-21 · The inhibitor of iron ore uses the sodium silicate, tannin and sodium lignosulfonate, and their inhibitory effect is the best when the pH value is 8-9. In terms of the ore properties of hematite ore, the reverse flotation method is more advantageous as the method used for the extraction of iron from hematite than the positive flotation method.
