2.1 Iron ore tailings. Two mine tailings were used as aggregates in this study, both from the mineral processing of iron ore in Minas Gerais state, Brazil. The first is obtained from jig concentrator devices, used to separate particles within the ore body, based on their specific gravity (relative density); it has particles between 9.0-0.3 mm.

The iron ore tailings have been applied as fine aggregates during the UHPC production, and the mechanical property of the designed UHPC is comparable to the control UHPC when the substitution of ...

As the demand for metal minerals grows, the number of mine tailings increases dramatically worldwide. Toxic heavy metals (HMs) in tailings tend to migrate into the environment and cause serious damage to the surroundings. Possible eco-friendly solutions for the in situ stabilization of HMs in tailing ponds are required to reduce their mobility. Leaching tests were performed with …

Iron ore tailings. A number of representative iron ore tailing samples were acquired from different locations of the dry tailing disposal areas (cf. Fig. 2).As illustrated in Fig. 3, the tailings were loosely dumped as piles; thus, their sampling did not necessitate any particular practice and merely involved filling bags with a hand shovel.A total number of 16 tailing samples, namely T1 to ...

The beginning of the tailings filtration operations in Vargem Grande is another step in stabilising iron ore production and on the way to the return of the production capacity of 400 Mt/y at the end of 2022, says Vale. The planned Vale operations mainly include thickeners and filtration plants using vacuum disc filters.

Iron ore tailings (IOTs) are a form of solid waste produced during the beneficiation process of iron ore concentrate. In this paper, iron recovery from IOTs was studied at different points during a process involving pre-concentration followed by direct reduction and magnetic separation. Then, slag-tailing concrete composite admixtures were prepared from high-silica residues.

With advent of novel technologies, mining companies are now figuring out ways to extract valuable metals from tailings. In gold, copper sulfide and iron ore tailings, the potential of extracting minerals is an opportunity. Reprocessing tailings to collect the valuable minerals can be a cost-effective approach compared to processing material.

iron ore was 2,850 million tons (approx.) with an Indian contribution of around 230 million tons. 2. The unavailability of cost-effective technology for the extraction of iron ore leads to the generation of a huge amount of waste. 3. The stripping ratio in Indian iron ore mine ranges from 1–3:1. 4. Tailing waste is the
