Iron ore tailing is a major solid waste requiring advanced recycling methods because ore tailing powder is polluting air and water resources For instance about 300 million tons of tailings are disposed yearly in 1229 iron ore tailings dams in the Hebei province in China Iron ore tailings can be recycled as functional materials because these tailings are similar
·Tailings constitute waste crushed rock particles resulting from ore processing exhibiting highly variable characteristics dependent on ore composition and extraction processes Kossoff et al 2014; Li and Coop 2019 The past few decades have witnessed a substantial surge in tailings volume due to increased mineral and metal
·Experts believe mine tailings could provide a new source of metals and minerals critical to the energy transition while also cleaning up the environment The type of extraction method that can be used on mine waste depends on the mineral deposits the tailings come from and what processing approach was used to generate them says
·Rapid economic development and increased demand for mineral products in China have led to extensive extraction of various ores resulting in significant environmental challenges associated with the generation of industrial solid waste particularly iron tailings Despite being a major mining nation China faces issues of

The released water and metal rich tailings flowed first into Polley Lake and then down Hazeltine Creek into Quesnel Lake Surface water samples collected in the affected water bodies showed elevated levels of suspended solids chromium copper iron and phosphorous during 2014 but the levels had returned to normal by 2016 [1]
·Recovery and preparation of high grade silica from iron ore tailings by S HGMS coupling with acid leaching technology Description of separation mechanism and leaching kinetics During the process of equipment operation the two superconducting magnets could produce a magnetic field [51] Steel wool was filled into the high gradient
·Refractory iron ore is often discarded as tailings This causes a great waste of iron resources In this paper the flash roasting magnetic separation process was designed by combining the magnetic separation process of magnetite and the process mineralogy of iron tailings The flash suspension roasting effects with 3 4 s roasting time
·With advent of novel technologies mining companies are now figuring out ways to extract valuable metals from tailings In gold copper sulfide and iron ore tailings the potential of extracting minerals is an opportunity Reprocessing tailings to collect the valuable minerals can be a cost effective approach compared to processing virgin material
Fine iron ore tailings slurry is commonly deposited in tailings storage facilities across the Pilbara region of Western Australia Many of these mines process ore from a combination of deposits such as Bedded Iron Deposits BID Channel Iron Deposits CID and Detrital Iron Deposits DID mixing the feed to obtain the product under contract
·Jig machine processing 30 2 coarse iron ore; Shaking table separating 2 fine iron ore particles; Spiral chute processing iron ore with low mud content 4 Iron ore dewatering equipment The iron ore mine dewatering operation divides into two parts concentrate mine dewatering and tailings mine
·Pre concentration followed by magnetization roasting and magnetic separation process was well recognized to be very effective in recycling iron from iron ore tailings An iron concentrate
·Pre concentration followed by magnetization roasting and magnetic separation process was well recognized to be very effective in recycling iron from iron ore tailings An iron concentrate containing % Fe with a total recovery of % was produced under the optimal experimental conditions roasting temperature 540°C;
·The final stage in iron ore processing is ironmaking where the iron ore is transformed into molten iron through a process called reduction The most common method of ironmaking is the blast furnace route In a blast furnace iron ore coke carbon and fluxes limestone or dolomite are loaded into the furnace from the top
