The XRD (X-Ray Powder Diffraction, D/max 2550PC, Japan Rigaku Co., Ltd) pattern of the tailings is shown in Fig. 1-a, which indicated that iron existed in the forms of magnetite and garnets (mainly andradite (Ca 3 Fe 2 (SiO 4) 3) and grossularite (Ca 3 Al 2 (SiO 4) 3)), and quartz was the main gangue mineral.However, garnets (andradite and …
In this study, a representative sample was obtained from Uckopru mine in Türkiye in order to beneficiate fine-sized chromite tailings. Physical and chemical analyses showed that while the whole tailings contained l2.80%Cr2O3 ( by weight), the particle size fraction of minus 38 microns contained 25.20%Cr2O3 (33.20% by weight) and the particle size …
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 …
Safety problems have concerned many researchers studying tailings dams in recent years, as they have a high risk of failure due to liquefaction. Existing analysis of liquefaction in tailings within a critical state framework has relied on the critical state line (CSL) being unique in the volumetric plane. However, recent advances have highlighted …

grade iron ore fines can be upgraded by means of STET tribo-electrostatic belt separator. The STET dry electrostatic separation process offers many advantages over traditional …
Offshore tailings disposal is one of the methods of mine tailings management allowed in the Philippines. Although there have been incidences of poorly engineered offshore tailings disposal by some ...
Following tailings dam failures in Brazil and elsewhere, including the aluminium sludge spill at the Ajka mine in Hungary in 2010, Philex Padcal in the Philippines in 2012, the Mount Polley mine in Canada in 2014, and the Cadia mine in Australia in 2018, there is a renewed sense of urgency from industry, civil society, and …
In India, the tailings of iron ore beneficiation are dumped in slime ponds, which is a major environmental concern. In the present study, a new beneficiation circuit was designed to recover the valuable minerals from the tailing effectively. The present study involves the characterization of three different samples using chemical, particle size, …
Iron tailings are the remains of solid waste after iron ore concentrates are selected by mineral processing technology. For a long time, iron tailings are disposed through accumulation and burial ...
For decades, tailings have been known as a necessary evil in mining. World Mining Frontiers writer Andrea Valentino talks to Sunil Tripathy, an expert in mineral extraction at the University of Lorraine, about how new fines dry magnetic separation (FDMS) could finally put tailings out to pasture, and investigates the impressive work …
The iron ore tailings acted as a filler and nucleating agent for the hydration reactions. ... with the objective of obtaining a waste rich in silica and a waste material rich in iron. A high intensity wet magnetic separator was used: Model WHIMS 3X4L from the Manufacturer Carpco Inc, with an electric current of 7 A, equivalent to a magnetic ...
