Mining operations can generate enormous amounts of waste (i.e. waste rock and tailings) that must be managed and handled in a way that avoids negative environmental impact. In Sweden, the mining industry accounts for over 80 percent of the total waste production each year. However, not all waste is to be considered harmful to the environment.
What is Mining and Mineral Processing? Mining describes the digging-up and removal of ore-containing rocks, either from large surface pits or underground workings. ... Heap leaching is an alternative process used …
Metal mining and processing have centuries-old tradition and remnants of these activities such as waste heaps, can be found worldwide (Adams et al., 2007, Adlassnig et al., 2012, Andráš et al., 2012, Medas et al., 2012, Pyatt et al., 2000).
The residual piles from heap leaching and excavated waste rock, and spent rock from an in-situ leaching, are also forms of mining and mineral processing wastes. …

These were followed by further processing, alloying, casting, shaping etc., eventually leading to the export/trade/use of the metal products (Hauptmann, 2007; page 7, his Figure 2.1). ... describe the two types of metallurgical mining waste-spoil heaps recognised and mapped, and in particular how they differ in their overall morphologies ...
Washery wastes result from the coal separation process. They account for about 80% of the total waste mass on average, which are subdivided into the following groups: (1) tailings or slurries generated from flotation processes, and their sizes are finer than 1 mm in diameter, (2) fine-grained waste produced from sedimentation procedures …
Among these are gases, dusts, sludges, slags, slurries, solutions and massive solid mineral materials such as mining overburden waste, ore processing tailings and residues, coal washer rejects and coal combustion fly ash. ... Recovery of the copper from the old dumps and from specially designed heaps by percolation leaching with …
At the same time, various types of waste are produced, including both mining and processing wastes, with diverse effects on human health and the environment [2, …
The heaped material consists of sulphide-bearing tailings from a processing plant of a lead–zinc mine. Mine waste material was deposited in the water phase after separation of mining ores in a flotation process. The tailing impoundment is partly covered with coarse sand and topsoil.
Our study proved that the disturbance brought about by the former mining and processing of metal ores led to the formation of species-rich understory with high frequency and cover of naturally-valuable species. ... With the development of metallurgical technology, waste heaps produced by earlier mining operations, but still rich in metals, …

The fluorine concentration in water under the waste heaps exceeds the MPC only for the "Mezhyrichanska"mine (by 2 times). The determined correlation coefficients are high, positive (r = 0.78-0.99) and evidence of the toxic components spread in water under the waste heaps throughout the entire coal mining region.
Massive tailings ponds and waste heaps are a testament to the industry's significant environmental footprint, presenting challenges from land degradation to groundwater contamination. ... of scarce resources but also significantly mitigates the …
The purpose of this paper is to review the progress made towards pollution and waste minimisation by the mining industry. The paper examines certain methods of pollution control used for air, land, water, tailings, sulphur and noise by the mining and mineral processing industries, drawing upon case study analysis in the Australian …
Figure 3 – Waste rock from an open pit operation has a wide range in particle size, and significant variability from one location to the next within the stockpile.. Spent Heap leach. In heap leach mining operations, rock …
Mining waste comes from extracting and processing mineral resources. It includes materials such as topsoil overburden (which are removed to gain access to mineral resources), and waste rock and tailings (after the extraction of the valuable mineral).

Western Małopolska, located in southern Poland, is one of the oldest regions of mining and processing of metal ores in Central Europe. These activities have lasted there for centuries, leaving traces, such as old heaps of waste rock (Aleksander-Kwaterczak and Ciszewski 2013; Stefanowicz et al. 2014). The heaps are small, …
The mining industry is globally criticized for generating large amount of solid wastes often with a potential environmental impact. This study presents a feasible approach of recovering residual coal from coal mine waste rocks (CMWR) and reusing the derived tailings to produce ecofriendly fired bricks.

Develops a set of principles and discusses implications for practise. Finds that future trends in mining and processing may compound the challenges. …
Waste generated by the hard coal mining and processing industries pose significant environmental hazard through, among other things, impacting water and soil. The process that is particularly ...

Mine waste material was deposited in the water phase after mining ores had been separated in a flotation process. The heap is bordered to the north and south by a dam consisting of fine to medium graded sands, whereas the finest material (silt and fine sand) is located in the centre of the heap (Graupner et al., 2007).
