What Are Tailings Ponds Environmental Impact Alberta

Tailing ponds are also used to enable water to separate from the tailings. Water from the tailings ponds is recycled back into the extraction process reducing the use of fresh water from the Athabasca River and other sources. Oil sands mining operators recycle 75 of water used.

James G. Speight in Heavy Oil Recovery and Upgrading 2019 5.5 The Oleophilic Sieve Process. An oleophilic sieve process (Kruyer 1983 2012) offers the potential for reducing tailing pond size because of a reduction in the water requirements. The process is based on the concept that when a mixture of an oil phase and an aqueous phase is passed through a sieve made from oleophilic materials

A custom approach to tailings managementCanadian

Today the materials in these tailing ponds are seen as valuable and potentially usable. If mines extract them they can use them. By using standard existing technologies such as dredges dewatering boxes and centrifuges in different ways miners are able to recover these materials and recycle them back into the process or as raw material.

Tailings Ponds 101 Oil Sands Magazine

 · Tailings ponds are massive earth structures used to store coarse and fine solids contained in the oil sands deposit and recover water back to the main processing plant. These ponds are temporary storage facilities and need to be reclaimed when no longer in use.Fine solids from tailings streams tend to trap large volumes of water making pond reclamation challenging at best.

The two tailings ponds contain a total of 20.3 million tons of tailings (Fig. 9.9 a) their average uranium concentration being 67 g/t. Because the barren process solutions were neutralised only to pH 7–8 (instead of shifting pH to 10.5–11) during the milling process the TDS content exceeds 20 g/l in the liquid phase of the tailings.The tailings ponds were built without any proper base

Oil sands tailings pondsEnergy Education

 · For every barrel of bitumen extracted from the oil sands 1.5 barrels of tailings waste is produced. This large volume of tailings requires a large area for storage and the sheer size of tailings ponds can be an issue as they encroach on wildlife territory. Efforts are being made to reduce the impact that tailings ponds have on the environment.
