Overview. Tailings are the byproducts that remain following the extraction and recovery of valuable minerals from mine operations. They are generated by a milling process and are a mixture of finely-ground sand-to silt-sized rock particles, water, and processing reagents.
The generation of enormous volumes of mine-tailing waste is standard practice in the mining industry. Large quantities of these tailings are also sources of kaolinite-rich materials that accumulate in slag heaps, causing significant environmental degradation and visual impacts on the landscape. The
As discussed previously, the primary types of solid wastes generated by the mining industry are overburden and waste rock from surface mining, waste rock from underground mining, bulk tailings from metal-ore and non-metal mineral beneficiation and milling processes and refuse from coal preparation-plant processes.
