What are oil sands tailings

In oil sands mining, tailings are what remain after the oil has been removed from the ore that was mined out of the ground. Tailings are made of sand, silt, clay, water, and some residual bitumen. How Tailings Are Stored . Companies store tailings in human-made tailings ponds, which they surround with monitoring systems. Once tailings are in

Oil sands tailings, composed of water, sands, silt, clay and residual bitumen, is produced as a byproduct of the bitumen extraction process. The tailings have poor consolidation and water release characteristics. For twenty years, significant research has been performed to improve the consolidation and water release characteristics of the tailings. Tailings ponds attract a lot of attention because there is currently about 77 square kilometres of oil sands tailings pond water in Alberta, according to the Government of Alberta. So while most people have heard of tailings ponds and seen photos, few know what purpose they serve and what the ponds actually contain. Oil sands tailings are the remaining sand, water, clay, silt and residual hydrocarbons left after the majority of hydrocarbons are extracted from the ore during our extraction process. Tailings are managed at Suncor’s Base Plant, as well as joint venture operations, Fort Hills and Syncrude. In situ production of oil sands bitumen does not It was, in fact, the first tailings pond in the industry, opened along with the original operations of Suncor predecessor Great Canadian Oil Sands in 1967. Tailings ponds are essential to the oilsands mining industry's water-based extraction process, according to the Alberta Energy Regulator, as they act as both holding basins from which One of the biggest challenges for oil sands mining companies is reclaiming fluid fine tailings. In oil sands open-pit mining processes, warm water is used to separate the heavy oil (bitumen) from the sands. The by-product of this process is a mixture of water, clay, sand and residual bitumen. Our approach to tailings management is guided by the Government of Alberta’s Lower Athabasca Region: Tailings Management Framework for Mineable Athabasca Oil Sands (TMF).Designed to monitor and manage long-term fluid tailings growth and reclamation in the Lower Athabasca region, the framework. provides policy direction to help manage tailings volumes;

The in-situ method of accessing oil sands resources does not produce tailings. Oil sands tailings are a mixture of water, sand, fine silts, clay, residual bitumen and lighter hydrocarbons, inorganic salts and water-soluble organic compounds. Tailings are stored in basins called tailings ponds, which allow the solids in tailings to settle. In oil sands mining, tailings are what remain after the oil has been removed from the ore that was mined out of the ground. Tailings are made of sand, silt, clay, water, and some residual bitumen. How Tailings Are Stored . Companies store tailings in human-made tailings ponds, which they surround with monitoring systems. Once tailings are in Tailings Directive 074 forces operators to capture fines, reduce tailings volumes and reclaim the landscape in no less than 5 years. Although the directive itself is quite straight-forward, meeting its targets has required oil sands mining operators to do what previously seemed almost impossible.
