Iron Mining Tailing

The biggest waste streams both in metal value and in volume in mining are tailings, which create long-term environmental liabilities to the companies (Wang et al., 2014) due to the potential for acid rock drainage generation (Simate and Ndlovu, 2014) from sulphidic tailings.Instead of considering the tailings only as an environmental challenge, the tailings …

For example, the Caren tailing impoundment in central Chile was retained by an earth-fill dam with a maximum height of 108 m (James et al. 2011), the Bahuerachi tailing dam in Mexico was designed with a maximum height of 100 m with the capacity of 200 million m 3 tailings, and the Yuhezhai iron tailing dam in Yunnan, China, was designed to a ...

The problem of sustainable disposal of tailings (MTs) that accumulate in tailing ponds and mine waste dumps is becoming more and more urgent every year [[1], [2], [3]].On the one hand, it happens due to the increase in production volumes of mining and metallurgical enterprises and the lack of effective technologies for handling these wastes.

What are Tailings? Tailings are a by-product of mining. After ore containing an economically-recoverable commodity is mined from the earth, that commodity is extracted in a processing plant or mill. After the commodity of value is extracted from the ore material, the resultant waste stream …

The rupture of the Fundão dam (Mariana, Brazil) resulted in various environmental and socio-economic impacts on riverside communities. However, the effects of iron mining tailings on the cultivation of vegetables and annual crops still need to be clarified, especially regarding the bioavailability of potentially toxic elements (PTEs), which may be exacerbated by the …

The mine tailing samples were collected from the Yaoposhan polymetallic mine in northern Guangdong province (24°31′16″, 113°04′29″). ... This is not surprising, as the Yaoposhan polymetallic mine produced raw iron ore at 0.05 million tonnes/yr and raw lead‑zinc ore at 0.03 million tonnes/yr at its production peak (Sun et al., 2018 ...

The iron mine tailing acted as a reinforcement agent, enhancing the mechanical strengths, about 40% of Young's modulus and 11% of tensile strength limit when compared to the properties of pure polymer, and an efficient flame-retardant activity in E1 samples. The replacement of HDPE pure by the composite HDPE/iron mine tailing in several uses ...

Finally, it was possible to add mining waste in soil-cement bricks to produce bricks that met all industry standards and thus adding value to iron tailing waste. Mendes et al. [43] carried out a technical and environmental assessment of iron ore tailing in fired clay bricks. The addition of iron ore tailings influenced the properties of bricks ...

Iron ore tailings were also used in other concrete applications. For example, Das et al. [13] studied the use of IOT to develop ceramic tiles and their study showed, that tiles produced at a maximum of 40% of IOT were superior in terms of scratch hardness and strength, compared to European standard specifications. In a related research, Yao et al. [14] produced a novel …

The fine tailing is generally generated during the step of desliming, which happens immediately before flotation. In Brazil, the generation of iron ore tailings (coarse or fine tailing) is estimated at 20-40% by the weight of the total …

Currently, approximately 1.4 billion tons per year of iron ore tailing wastes (IOT) are generated, mainly in Australia, Brazil, and China. This work describes the characterization and...

1 Introduction. Peak carbon dioxide emissions and carbon neutrality are the main development goals of all countries in the world (Nielsen et al., 2019; Yan et al., 2020).Cement manufacture, as one of the traditional industries with heavy energy consumption and emission, generates 5%–8% of the global CO 2 emissions per year (Turner and Collins, 2013; Mo et al., …

Tailings from iron mining are characterized by high concentrations of iron and manganese oxides, as well as high pH values. ... PTE contents extracted by USEPA 3051A in the non-impacted soil and in the mine tailing. Mine tailings that were deposited in the area (IA) after the rupture of the Fundão Dam presented greater amounts of selected ...

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 …

The mining sector is a very challenging sector.Particularly, coal and iron mines produce maximum overburden and tailing waste.Proper utilization of this waste in construction sites can reduce the maximum problems of land,water and air pollution.Hence, in this paper based on literature, waste is categorised and a few suggestions are provided for ...

It is currently unclear what the overall potential of extracting metals and minerals from tailing waste could be, but Jowitt believes there is value to be had. ... – as the breaching of the Brumadinho dam disaster, which killed 270 people at the Vale Córrego do Feijão iron ore mine in Brazil, demonstrated in the extreme. Targeting ...

The mining industry does, however, produce enormous volumes of waste. The amount of mine waste produced is of the same order of magnitude as that of fundamental Earth-shaping geological processes, some several thousand million tonnes per year (Fyfe, 1981, Förstner, 1999).The chief waste stream is tailings, which are often stored in impoundments …

1. Introduction. Iron (Fe) ore production is one the most important mining activities worldwide, with an annual production of approximately 3000 Mt. (Lu, 2015).However, Fe mining also generates tons of tailings, which are usually stored in dams (Glombitza and Reichel, 2014; Lu, 2015; Zheng et al., 2011).The tailings are mainly composed of fine particles that are rich in …

Compounds based on iron mining tailing dams and activated ...

In recent decades, the global mining sector has expanded rabidly in response to the rising need for metals and minerals. The mining industry plays a critical role in achieving the UN's Sustainable Development Goals (SDGs) 17 ("ensuring sustainable consumption and production patterns"), as it heavily consumes natural mineral resources and generates massive mining …

The ultra-low-grade magnetite, with a lower than 20% total iron content, has been extracted by open-pit mining and processed massively since 2001 in Hebei Province, China [5,6]. Changhe Mining Area is an important mining area in the region and has proven reserves of more than 2.3 billion tons of ultra-low-grade iron ore .

However, some similarities were observed for samples of gold and iron mining tailings, gold and Cu/Zn tailings, iron, and gold tailings, and among Pb/Zn, iron, and vanadium tailings, as we can see on the similarity matrix in Fig. 3b. These observations reaffirm the importance of conducting analyses for each tailing that will be studied since it ...
