During production of calibrated (sized) ore, more than 50 % of the generated fines and rejects (Slimes) cannot be directly utilised in iron making due to its unfavourable granulometry, low iron content, high alumina and silica content. Approximately 10–20 % of the process plant input is discarded as slimes into slime ponds/tailing dams. Tailing dams are now …
Strategies like extracting rare earth elements and making geopolymers from tailings were explored. Techniques like bioleaching and mechanical activation can improve tailings …
More importantly, the corresponding tail contained ~45% Fe. It was concluded that this novel process may be effectively used to recover iron values from low-grade hematite tailings. Key Words: Iron ore slime, Fe Recovery, HGMS,Yield & Noamundi. INTRODUCTION. India is endowed with huge iron ore deposits and occurs mostly as oxides in nature.

The two prominent methods for mine wastes management or storage are dams and dumps, according to Blight [].Mine tailing impoundments and dam failures are very common, and many literatures have reported this [13, 14] as a cause due to the geotechnical behaviour of tailings.The Fundao dam failure in 2015 [], Brumadinho dam disaster at Corrego do Feijao iron …
Iron ore is essential in steel making; however, high-grade ores have diminished, making low-grade ores inevitable. These low-grade iron ores need further beneficiation to upgrade the iron content. Currently, traditional physical and chemical methods are utilized and are not environmentally friendly. Bio-beneficiation techniques have emerged as a sustainable …
Iron ore tailings (IOTs) are an important solid waste in the mining industry, which can pollute the environment and endanger human health. However, the disposal and high value-added utilization of iron tailings have always been a challenge. Notably, superconducting high-gradient magnetic separation (S-HGMS) technology is a promising technology in mineral …
The straw-type biomass, as a green and alternative reductant for the suspension magnetization roasting (SMR) of iron ores, is proposed. The roasted products are investigated at a roasting temperature of 750 °C, the roasting time of 7.5 min and the biomass dose of 25%. The iron phase results indicate that hematite ores were reduced to magnetite by the biomass, and …
The beneficiation of low-grade iron ores is a key research and development topic in the mineral processing industry. The gradual exhaustion of high-grade iron ore reserves, and rising consumer iron and steel demand …
Use ore sorting equipment to concentrate ores and cut process costs. There are many ways of improving recovery processes for a wide variety of ores using sorting equipment.
