The increasing annual emissions of iron ore tailings have proved a great threat to the natural environment, and the shortage of natural river sand, as well as the pursuit of sustainable development materials, provides motivation to reuse iron ore tailings as a fine aggregate in concrete. Due to the significantly different properties of iron tailings sand …Tailing beneficiation of iron ore has been addressed either by flotation or wet high intensity high gradient separation. The present study aims to recover iron values from discarded slime containing assay ~56% Fe, ~6.5% SiO2, and ~7.0% Al2O3 from Noamundi processing plant by using high gradient magnetic separator (HGMS).

Tianjin 300191, China) Keywords: iron ore tailings resources; development and utilization of pattern; circular economy; overall utilization . Abstract. Through the analysis of current development and utilization of iron ore tailings resources in China, we can summarize the present development and utilization pattern of iron ore tailings resources.Mining is an important industry, accounting for 6.9% of global GDP. However, global development promotes accelerated demand, resulting in the accumulation of hazardous waste in land, sea, and air environments. It reached 7 billion tonnes of mine tailings generated yearly worldwide, and 19 billion solid tailings will be accumulated by 2025. Adding to this, the legacy of environmental …

As the most abundant industrial waste material, the tailings from mines in China have amounted to a total mass of more than 20 billions tons, which occupy a lot of precious farming land. The utilization of tailings as new resources has become one of the hotspot topics and presents a real challenge for the Chinese mining industry. ThisAnd so far, the accumulated quantity of tailings has reached 60 billion tons and occupies 1.1 million hectares in total. Among all tailings, the amount of IOT produced in 2018 alone reaches up to 0.475 billion tons in China, which accounts for 39.22% of all tailings, as shown in Fig. 2.
