Day, S., Sexsmith, K., Millard, J.
BHP Billiton Diamonds Inc (BHPB) has been mining kimberlite from several pipes at the Ekati Diamond MineTM located 300 km north of Yellowknife since 1997. Processing of kimberlite produces coarse kimberlite rejects (CKR, 0.5 to 8 mm) and fine tailings (less than 0.5 mm). The CKR are trucked to...

Many operating hard-rock sulfide mines are predicted to require perpetual post-closure management to prevent environmental degradation. Causes include evaporative concentration of metals and other solutes in pit lakes, and acid rock drainage from sulfide waste-rock, tailings, and pit benches....

Amylopectin-graft-hydrolyzed-poly(methyl acrylate) (AP-g-H-PMA) Flocculants for the Treatment of Oil Sands Tailings
DownloadSpring 2020
The extraction of bitumen from the Alberta oil sands reserves has long been a major economic contributor to the Canadian society, but the impact this industry has had on the environment has raised concerns worldwide. The main problems are how to reclaim the area and reduce the number of tailings...

An environmental study of the Athabasca tar sands: Report and recommendations to Alberta Department of the Environment
Download1973
Intercontinental Engineering of Alberta Ltd.
The following was the general concept of the work for which the Study was commissioned: • Identify the various methods that could be used for oil extraction and their comparative merits with respect to minimum adverse effects on the environment. • In considering the Clark method of tar sands...

Anoxic limestone drains (ALDs) have been widely used in the passive treatment of acid mine drainage (AMD), but their effectiveness has often been less than anticipated. Iron hydroxide often precipitates around limestone particles and inhibits neutralisation. To determine the conditions under...

An Integrated Optimization Model for Strategic Open-Pit Mine Planning and Tailings Management
DownloadFall 2014
Badiozamani Tari Nazari, Mohammad Mahdi
A strategic mine planning model determines the best order of extraction and destination of material over the mine-life, in a way that maximizes the net present value of the produced minerals. In case of oil sands open-pit mining, further processing of the extracted oil sands generates massive...

An Investigation of the Methylene Blue Titration Method for Clay Activity of Oil Sands Samples
Download2014-12-04
Currie, R., Mian, H., Bansal, S., Khan, I.
The purpose of this report is to use a design of experiment (DOE) approach to examine the main factors affecting the determination of methylene blue index (MBI) values for oil sands samples. The methylene blue titration of clays has become a principle tool to assess extraction efficiency of oil...

Wels, C., Lefebvre, R., Robertson, A. M.
Air movement and associated oxygen transport through waste rock dumps has the potential to significantly enhance the rate of oxidation of pyrite-bearing material. While this is a desired outcome for most heap leach operations, airflow in waste rock storage facilities can result in significant...

Desmier, R., Dixon, J., Macdonald, B. C. T., Melville, M. D., Waite, T. D.
The acidic and metal rich waters that are generated from acid sulfate soil (ASS) drainage can have damaging impacts upon ecosystems. The most obvious impact has been the discolouration of water and occasional fish kills. ASS’s produce these acidic and metal rich waters when pyrite in soil is...
