tailings.info what are tailings? their nature and productiontailings 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 100% efficient, nor is it possible to reclaim all reusable and expended processing reagents and chemicals. the unrecoverable and uneconomic metals, minerals, chemicals, organics and process water are discharged, normally as slurry, to a final storage area commonly known as a tailings management facility (tmf) or tailings storage facility (tsf). not surprisingly the physical and chemical characteristics of tailings and their methods of handling and storage are of great and growing concern. tailings are generally stored on the surface either within retaining structures or in the form of piles (dry stacks) but can also be stored underground in mined out voids by a process commonly referred to as b see full list on tailings.info the process of beneficiation of run of the mine ores and subsequent disposal to surface containment facilities exposes elements to accelerated weathering and can consequently increase their mobilisation rates. the addition of reagents used in mineral processing may also change the chemical characteristics of the processed minerals and therefore the properties of the tailings and waste rock (ec 2004). the processing of hard rock sulphidic bearing ores is just one example of accelerated weathering. in this case the sulphide minerals more readily oxidise in the tailings facility as a result of the size reduction from milling increasing the surface area and thus exposure of the tailings to air and water. acid generation and metal mobilisation occur that can find their way into the surrounding environment through runoff or seepage. this phenomenon is a well known problem affecting the mining industry and is commonly known as acid mine drainage (amd) or acid rock drainage (ard) (garcia, b see full list on tailings.info the disposal of tailings is commonly identified as the single most important source of environmental impact for many mining operations (vick 1990). this is not surprising when considering that the volume of tailings requiring storage can often exceed the insitu total volume of the ore being mined and processed. over the last century the volumes of tailings being generated has grown dramatically as the demand for minerals and metals has increased and lower grades of ore are being mined through advances in extraction and processing technology. in the 1960s 10s of thousand of tonnes of tailings were produced each day and by 2000 this figure had increased to 100s of thousands (jakubick, mckenna et al. 2003). today there are individual mines producing in excess of 200,000 tonnes of tailings per day. understanding the mineral processing techniques can help to determine how tailings are produced and the challenges associated with their storage. run of the mine ore is physically reduced see full list on tailings.info tailings characteristics can vary greatly and are dependent on the ore mineralogy together with the physical and chemical processes used to extract the economic product. ritcey (1989) reported that tailings of the same type may possess different mineralogy and therefore will have different physical and chemical characteristics. the tailings characteristics have to be determined to establish the behaviour of the tailings once deposited in their final storage location and the potential short and long term liabilities and environmental impacts. once the likely characteristics of the tailings are determined from laboratory and pilot plant tests, the necessary design requirements can be identified to mitigate environmental impact as well as determine optimum operational performance. liberation of water from the tailings once discharged in a facility and the volume available for return pumping to the processing plant is an important design parameter influencing the water balance of a mini see full

specific environmental impact of waste depends heavily on the materials composition, type of ore mined, and the way the ore is processed. for example, gangue and tailings from mining heavy metals could have a high concentration of sulfides which could cause acid rock drainage to occur. gold ore mining tailings run on flexicone170 centrifugal gold ore mining tailings run on flexicone170
