Mine Waste Transfer and Disposal Methods - Mine Tailings, Gangue
Mine tailings are reused for producing clay, tiles, glass, and concrete. Mine water is treated and then used for dust and particulate suppression, agricultural/industrial use, and as a coolant. Despite numerous recycling methods, the majority of mine waste is still stored in facilities or waste sites.
Mineral Processing and Recycling | Aalto University
Mineral Processing and Recycling Among the major issues facing our modern, civilized world is an ever-increasing demand of raw materials. For that reason, the aim of our group is to find technological solutions to address the current needs related to the production of inorganic raw materials, whether from primary or secondary sources.
Recycling Basics | Reduce, Reuse, Recycle | US EPA
Recycling includes the three steps below, which create a continuous loop, represented by the familiar recycling symbol. Step 1: Collection and Processing There are several methods for collecting recyclables, including curbside collection, drop-off centers, and deposit or refund programs.
REPROCESSING AND TAILINGS REDUCTION
As a result, CDE has designed its EvoWash™ and AquaCycle™ combination to slot into a wet processing circuit for tailings dewatering, while its Plate Press filtration system, which has been in demand as of late, is able to be incorporated into the mix and achieve higher levels of water recovery and dry stacking.
Converting Tailings Dumps into Mineral Resources | Energy
Similarly, tailings dumps arising from the processing of chrome ore in the Lower Group reefs of the BC are also being retreated to recover PGEs. Several commercially profitable enterprises have also been set up with the sole intention of retreating tailings dumps arising from South Africa's Witwatersrand gold processing operations.

Tailings.info The website focused at tailings related
The word tailings is sometimes applied to include coarse mine waste. For this website the term tailings refers to the slurry waste output from the processing plant. The properties of tailings are dependent on the ore body being mined, the grinding and processing circuits, the reagent properties and the thickening process prior to disposal.
How to handle mine tailings safely and sustainably
views dry filtered tailings as the most viable and long-term solution for tailings handling, as it not only helps in recycling significantly more water to
LKAB plans tailings recycling centre - Mining Magazine
Swedish mining company LKAB plans to build a 50-hectare industrial centre that will use fossil-free processes to recycle tailings from LKAB’s iron ore production into phosphorus products and rare earth elements. Residual products from LKAB's mines include both phosphate minerals and so-called rare earth metals
How to generate value from tailings with reprocessing to be
A standard method of reprocessing involves dragging tailings from an existing dam back to the concentrator and using required mineral processing solutions to liberate the valuable metals. The discarded tailings are then dewatered and dry stacked, and the water recycled within the plant or properly disposed back to nature.
The Tailings Center - Mining Engineering
After extraction and beneficiation, the residuals from mineral recovery are normally discharged as a hydraulic fill (aka slurry) composed of finely ground gangue (sub-micrometer to sand-sized particles), chemicals, and process water into a TSF impoundment where solids slowly consolidate, releasing water much of which is returned to the processing circuits. Although termed tailings ‘storage’ facilities, these facilities are not temporary, and cannot be discarded at the end of useful mine

UA mining-tech startup picked for international challenge
A Tucson-based startup aims to turn mine tailings into usable products with technology invented by University of Arizona researchers, and it’s going after a big prize to advance its efforts.
3 Methods of Tailings Processing - Mining-pedia
Tailings Filling Goaf. Tailings filling goaf is the process of refilling the processed tailings waste material back into the goaf area, which can achieve the functions of protecting the landform and reducing the cost of the tailings dam. At present, there are two main methods for tailings filling goaf: 1) Full Tailings Cementing and Filling
Reclaiming tailings sustainability | Global Mining Review
The standard tailings processing model takes time, but this solution successfully reduced tailings residence time with a total solution realised through Weir Minerals equipment. Multiflo® pump barges mounted with Hazleton® submersible slurry pumps extract the target fluid tailings that feed high-powered, land-based, Weir re-locatable pump houses.
The influence of temperature and SiC content on the recycling
Iron ore tailings (IOT) are common wastes in industrial iron processes, which are harmful to the environmental and industrial development. Therefore, developing an efficient process for the recycling and utilization of IOT is of extreme importance.
Tailings mineral processing - Royal IHC
Legacy tailings are often considered as waste. However, reprocessing tailings can turn the perceived waste into a valuable resource. Royal IHC’s in-house mineral processing knowledge, combined with our strategic partnerships, can provide complete solutions for extracting valuable materials from mine tailings.
Tailings & Water Management | McLanahan
Every aggregate or mineral producer who processes rock, crushed stone, sand, coal, limestone, gold, etc. ends up with tailings. Tailings are the unavoidable and undesirable ground rock and process washwater left over from the processing plant after the desired material has been separated.
New Tailings Reprocessing Technology Has Environmental Benefits
Tailings may be dumped in or near water or transported by wind or water to contaminate the surrounding area. Mine sites typically manage tailings by constructing ponds secured by dams. However, some mining companies are figuring out ways to turn tailings to profits with novel reprocessing technologies to extract valuable metals from the waste.
How Is Mining Waste Recycled? - Ecocycle Australia
Recycling The Smaller Stuff Tailings are the finely ground rock left over after mineral processing and they are mostly stored as a watery mix in tailing dams. Despite big improvements in the construction of tailings dams, they can fail, often with disastrous consequences. Some mines reduce this risk by ‘thickening’ the tailings.
