Tailing, in context to mining, is defined as the waste or non-economic by-product generated during mining activities, processing of minerals, and other materials that contain small amounts of residual valuable minerals, chemicals, water, and heavy metals (Adiansyah et al. 2015).Studies indicated that the process of mineral exploitation and …

The PERI associated with each HM in mine waste soil analysed in the present study showed that all heavy metals had low ecological risk at the tailing dams of Kitwe and Mufulira (Table 6).

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 …

Introduction. Tailings consist of ground rock and process effluents that are generated in a mine processing plant. Mechanical and chemical processes are used to extract the desired product from the run of the mine ore and produce a waste stream known as tailings. This process of product extraction is never efficient, nor is it possible to ...

In mining, tailings refer to the residual waste material that remains after the desired minerals have been separated from the ore during the mining process. These typically consist of finely ground rock particles, water, and traces of chemicals used in the …

Spain has a long mining tradition dating from pre-historic times up to the present day. The cessation of mining activity has generated a large amount of mine wastes, most of which represent geochemical hazards. Mine tailings are watery sludge composed of medium-to-fine-grained material, resulting from grinding and mineral …

Upstream tailing dams, which are commonplace, can easily lead to major accidents under seismic excitation. However, the dynamic response characteristics and causes of instability failure of tailings dams are yet to be investigated fully. In the present study, shaking-table tests were conducted to determine the acceleration, pore pressure, …

Our study comprises four tasks, summarised in Table 1. The first task is to clarify the target of transparency in tailings management. For this, we use the GTR Standard as a reference point. Our second task is to understand existing public disclosure requirements in voluntary standards and schemes endorsed by the global mining …

A typical mine tailing particle digital image is presented in Fig. ... Table 1 was used as an aid in assigning the mine tailing grains to a specific category. The average roundness value was 0.29, which corresponds to the subangular. These grains have slightly rounded corners and blunted edges due to the extraction process.

Abstract. Mine tailings—the residue remaining after mineral processing—represent a serious risk to the natural environment, and the failure of tailing storage facilities has caused some of the ...

Similarly when mine tailing is mixed with 8% lime, there is an increase in strength but not as significant as observed with cement mixed tailings (see Table 7, mix IDMT/8/0/0). However when mine tailing is mixed with cement, lime, and fly ash, maximum UCS value was about 1801.17 kN/m 2 after 28 days curing period and 3857.06 kN/m 2 …
