At the federal level, the Government of Canada may be responsible for regulatory decisions specific to tailings management if they involve uranium tailings (Canadian Nuclear Safety Commission), navigable waters (Transport Canada), fish bearing waters and fisheries (Fisheries and Oceans Canada and Environment Canada), environmental matters of international and inter provincial concern
In follow up two international workshops were organized by Syncrude and WISMUT on Stabilisation of Fine Tailings Workshop No. 1 The scientific basis took place in Edmonton, Canada, May 26 27, 1999 and Workshop No.2 Practice and Experience was held in Chemnitz, Germany, June 23 25, 1999 .
Jul 19, 20190183;32;The dry stack method eliminates the storage pond and dam associated with conventional tailings facilities, the nonferrous mining company said Thursday. It has been successfully used in four mines in the northern United States and Canada having similar climates and has been permitted at two mines in the western United States, Twin Metals said.
Tailings, A Lasting Oil Sands Legacy. WWF Canada, October 2010 17. Deposits are worked with a discer to increase the rate of drying (Suncor February 2010c, response to question 121). The process is intended to produce final deposits with 20 to 35% fluids content within 6 and 20 days of being deposited.
Design and Evaluation of Tailings Dams that are prepared in anticipation of late impoundment expansion can develop cracks if they are allowed to dry before being covered with tailings. 2.2.2 Ring Dike Impoundments Where natural topographic depressions are not available, the Ring Dike configuration may be appropriate (Figure 6).
Tailings Dam. IVAC PV500 Winter Rock/Sand Tailings Pump Vacuum. THE PROJECT. Kidd Creek Mines near Timmins, Ontario, Canada, is a world class mining operation. The mine began operation in 1966, producing copper, zinc, indium, cadmium, silver and sulphuric acid. The deposit is one of the largest and richest volcanic sulphide deposits in the world.
They are generated by a milling process and are a mixture of finely ground sand to silt sized rock particles, water, and processing reagents. Tailings Management is a fundamental component in the design and operation of mining projects in Canada.
Tailings can be discharged using subaqueous (below water) or subaerial techniques. Subaerial deposition is more common than subaqueous as it forms a sloping beach toward the reclaim/decant pond. Subaerial can be done from single or multiple discharge points and can be
It is typically a straightforward process to create dry stackable tailings from the sand tailings, and they are often used to build the containment for the remaining fluid fine tailings. Another common practice in the surface mined oil sands industry is to define sand as mineral particles larger than 44 micrometres ( 181;m).

Tailings training and governance; We take a holistic approach to overall tailings management with our multi disciplinary capability. Our services go beyond the scope of individual projects as we aim to be a trusted advisor for all tailings management related matters.
The modern tailings designer has a range of tailings products to choose from depending upon how much water is removed from the slurry prior to discharge. The removal of water not only can create a better storage system in some cases (e.g. dry stacking, see below) but can also assist in water recovery which is a major issue as many mines are in arid regions.

Jul 19, 20190183;32;The company claims dry stack tailings are currently used at four mines in the northern United States and Canada with similar climates to Minnesota. It has also been permitted at two mines in the American West.
Aug 06, 20140183;32;The waste becomes tailings, and it gets mixed up with water, and its pumped out into this pond. The purpose of this pond, with an embankment around it, is to retain the tailings and allow them to drain as much as possible. Its basically sand sized particles,
Oil sands tailings ponds are engineered dam and dyke systems used to capture oil sand tailings. Oil sand tailings contain a mixture of salts, suspended solids and other dissolvable chemical compounds such as acids, benzene, hydrocarbons residual bitumen, fine silts and water.
In the case of dry tailings, seepage of water from tailings impound ments to groundwater is limited to avail able supernatant water. Surface manage ment of rainwater on impoundments can be engineered to limit ingress of water and reduce available supernatant water in tailings dams.
Tailings Ponds. Canada's oil sands industry is working to improve the management of tailings ponds, both in the monitoring of active tailings ponds and in developing technologies to move them into reclamation sooner. Tailings are a mixture of water, sand, clay and residual bitumen, and are the by product of the hot water treatment process used
DESERT PLACER GEOLOGY. After a storm in the desert, in some places you can find small pockets of gold in the gravel traps, under rocks and under boulders which rest on top of the caliche. Sometimes the gold is pounded directly into the caliche and needs to be removed with a pick or crevice tool.
Sep 07, 20170183;32;In the 1960s, Earle Klohn, one of the founders of Klohn Crippen Berger (KCB), recognized that applying water dam technologies to the design of large tailings dams for the new high tonnage copper mines in British Columbia, Canada, was problematic, because tailings dams are continuously constructed (raised and expanded) during the life of a mine, whereas water dams are
Sep 01, 20100183;32;The majority of the fines separate or segregate during tailings sand deposition and flow into the pond in suspension to form fluid fine tailings.
Dry Stack Tailings Facility (DSTF) Keno Hill District Mill Site The properties of the tailings that will be produced from the Flame and Moth ore zone are expected to be very similar to the geological and geotechnical properties of the Bellekeno ore zone tailings.
Tailings. COSIAs Tailings Environmental Priority Area (EPA) is focused on improving the management of oil sands tailings. Tailings are the sand, silt, clay and water found naturally in oil sands that remain following the mining and bitumen extraction process. Working
During its disposal, coarse fraction of the tailings typically settles out near the discharge point while the fines, which will become mature fine tailings (MFT), remain in suspension. Under the current tailings management schemes in oil sands industry, MFT are still being
