One of the most efficient ways of tailings reclamation is hydraulic mining. Our hydraulic mining solutions utilise high pressure pumping systems and specialised equipment to re-pulp tailings deposits, which allows for reprocessing. This, in turn, gives the opportunity to unlock the true value of tailings.

Tailings deposits are found everywhere in the world where there is ongoing or legacy mining activity. These man-made deposits can present challenges for the owners, but can also hold interesting opportunities. Either way, sustainable re-handling and reprocessing of tailings is becoming a more prominent part of mining operations.

reprocessing tailings and other 'waste' is CDE. An industry-leading manufacturer of wet. processing equipment for materials processors, CDE has seen a significant rise in proposal requests for dewatering and dry stacking equipment over the previous 12 months, according to Kate McCormick, Mining Sector Executive at CDE Meta.

According to the company, thanks to advances in separating, sorting, and crushing equipment, very small diamonds can be recovered from the residue of the original diamond-bearing ore. De Beers recovered 815,036 carats of diamonds from 6,133,799 tons of tailings in 2013 and expects to continue operations beyond 2030.

Tailings Management solutions. Metso Outotec Tailings Management is bringing change through dewatering, handling and reprocessing of tailings. No other OEM can provide the full solution that we can. Metso Outotec Tailings Management …

Given that the quantity of tailings produced each year through copper extraction alone totals 2.9 billion tonnes, and 1.6 billion tonnes for the …

Reprocess tailings. Really? Yes, really. If the technology exists today to remove up to 90% of water from mine tailings and, if a mining company is going to make that investment anyway to secure its future operations, then frankly, it is irresponsible not to consider reprocessing the tailings that currently sit in its TSFs.

Tailings reprocessing technology means higher demands on mining enterprise, especially in tailings test, technological innovation, energy-saving and capital investment. For the majority of mining companies, they can't afford these huge capital investment and …

In the actual production process, it is necessary to select the appropriate tailings reprocessing process and equipment according to the nature of the copper tailings, and recover copper from the waste rock and tailings, and multiple useful metals and non-metal elements such as gold, silver, iron, etc., to achieve efficient use of copper resources.

Tailings re-handling can benefit from dredging due to low OPEX and high production rates, which support the feasibility of tailings re-handling business cases. IHC is the market leader in dredging, with over 300 years of experience. We design and build a variety of standardised (Beaver®) and custom-built cutter and wheel suction dredgers (CSDs ...

Re-handling tailings with IHC dredgers. Tailings storage facilities (TSFs) that are (partly) submerged are inaccessible for conventional mining equipment. By using Royal IHC's dredge mining equipment however, tailings re-handling is still feasible and can be safely executed. Slurry transport is most cost-effective method of material transport.

For example, a tailings stream in an iron ore application could be thickened to 45-50 percent solids Newtonian slurry in conventional or high-rate thickeners. Conversely, the same tailings stream could be thickened to 65-70 percent solids non-Newtonian suspension using a paste thickener. Water Recovery

• Mining – Surface or underground operations with associated surface tailings, impoundments, and processing facilities, etc. • Resource extraction and processing (hard rock example) – Mining = Overburden, Waste Rock, Sub-Ore, and Ore • Ore - up to 13 percent REE or greater • Tailings - up to 0.5 percent REE or greater

These tailings contain lots of mercury polluting the environment, but also contain serious amounts of precious metals. Currently miners get from 4-35 grams per ton of ore. The ore is ground and mercury is added. Tailings are dumped. I will post some pics and videos for your entertainment and education.

With advent of novel technologies, mining companies are now figuring out ways to extract valuable metals from tailings. In gold, copper sulfide and …

With reprocessing, the mining companies can set the agenda to transform the tailings ponds from a liability into an asset. Whether driven by …

to the client. With this monitoring equipment, k nowing the phreatic surface within the impoundments will be of critical importance to the future geotechnical stability assessments of the facility. And monitoring the long-term drain down of the tailings and standing water levels will be important to the reprocessing mining plan.

Tailings is characterized by poverty, fineness and impurity, especially some refractory tailings. It is difficult to recycle them efficiently with common ore beneficiation technology and equipment, and it is impossible to maximize the recovery of useful minerals.
