Iron tailings are a common industrial solid waste, and with the development of society and continuous progress in ore dressing technology, the stockpile of iron tailings is increasing. The vast stockpile of iron tailings not only occupies a large amount of land but also causes serious environmental problems.
In this study, a pilot-scale experiment on the iron recovery from iron ore tailings was investigated using innovative technology of pre-concentration and …
In the Sivas-Divriği Iron Ore Concentrator, 600,000 t of tailings are discarded annually. There are already 1 million t of tailings deposited in ponds from the previous production activities. The presence of Co, Ni, and Cu in the tailings makes the beneficiation of those tailings attractive.
In this paper, a novel method to recover iron from iron ore tailing (IOT) was studied. The method was induced with carbothermic reduction, followed by magnetic flocculation separation (MFS) and conventional magnetic separation (CMS). The effects of reduction temperature, as well as the amount of coal and sodium carbonate on iron …

Mineralogical Characterization of Iron Ore Tailings from the Quadrilatero Ferrifero, Brazil, ... the fractions -37μm + 5μm of the studied tailings, with a potential recovery of 12% of the total sample ... pulp. Then, by dispersing air in the flotation machine, the particles of certain minerals attach to air bubbles and are
In order to comprehensively utilize iron ore tailings (IOTs), the possibility of using IOTs as raw materials for the preparation of cementitious composites (IOTCCs) was investigated, and IOTCC was further applied to mine interface pollution control. The mechanical properties, hydration products, wind erosion resistance, and freeze–thaw …
The tailing in a large lead-zinc-iron-sulfur multi-metallic mine has rich reservation in variety of metallic minerals. It has been difficult to recover because of all kinds of reasons. The challenges faced by lead-zinc ore beneficiation are, low grade and recovery of lead and zinc concentrate for fine disseminated grain size, high oxidation …
Similarly the process was applied to iron ore slime and the findings showed that it was possible to upgrade the iron ore tailings more than 63% from the feed grade of 50.98(%) by selective flocculation process. The detailed study using iron ore slime is under process. It will be communicated later.
technology based on the tailing composition is an important method for managing iron ore tailings. The recycling strategy for iron ore tailings is conducive to improving the regional ecological environment and promoting the coordinated development of resources and en-vironmental protection.
Efficient dewatering of iron ore tailings: creating more value from waste With our expertise and cutting-edge technologies for iron ore tailings, we are committed to helping you maximize water recovery while minimizing environmental impact.
The tailings blanket recycling machine is gravity separation equipment, suitable for the purification of various rare metal ores.
Metals recovery from tailings. Tailings are waste products of mineral processing, where target minerals or metals of an ore are separated from the unwanted gangue. Thus, the mineralogy of the orebody and selections made in mineral processing play a major role in the tailings characteristics and metal recovery possibilities.
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 …
The developed magnetic-gravity technology for processing of the tailing dump material ensures the production of iron ore concentrate with the total iron content of 65.9% and …
We have designed more than 100 tailings dams across the globe. Our track record includes tailings pipelines, storage dams, and impoundments.
Iron ore tailing/slime (-150 m) is produced after scrubbing and wet screening of a low-grade iron ore. Tailing beneficiation of iron ore has been addressed either by flotation or wet high intensity high gradient separation.
According to research by mineral processing firm , the quantity of tailings generated each year by the copper industry alone amounts to 2.9 billion tonnes, and iron-ore production adds a further 1.6 billion tonnes.
