Mature fine tailings density

These culture-based results are similar to the results of the present study, suggesting that the increased salinity may not have significantly affected the microbial abundances. However, vagaries of the weather i. The A and B polymers released a significant amount of water at the start of the experiment as evidenced by the saturated paper towel. The lime and gypsum sample did not develop an initial strength and coverage of the pan was more uniform than that for the FFT and polymer mixes. University of British Columbia Library.

Inline Dewatering of Oil Sands Tailings

Yabuuchi, Kawamura, Kosako and Ezaki a, Levels of carcinogenic , mutagenic , and teratogenic PAHs were substantially higher than guidelines for lake sedimentation set by the Canadian Council of Ministers of the Environment in Since this occurred in all of the samples, it suggests that the surface of these tailings desaturate at low suctions and could lead to the development of ARD soon after surface deposition. The start-up time was considered the time it took for the pH of each reactor to stabilize at the desired pH, while the operation time was the entire period of operation of each reactor Table 2.

The process of claim 1, comprising forming the network of ditches between the deposit and the sumps to channel the deposit water and rainfall or snow melt to the sumps.

I want to thank my lab and office mates, Shelir Ebrahimi who was always willing to trouble-shoot problems with me, Roger Yeyuan Xiao who trained me to take on this project and all of the other students who have helped me along the way: Passive remediation of acid mine drainage using bentonite clay: However, relatives of these two genera were not isolated at the end of reactor operation in any of the reactors, suggesting that the organisms isolated in the first isolation were not halotolerant or they were outcompeted by other organisms. Microbially-accelerated consolidation of oil sands tailings.
The pit deposition allows the tailings to expel water during settling which can then be manually decanted, allowing cracks to develop and drying to accelerate Sobkowicz, The concept to use phage therapy at an industrial scale has been proven for the mitigation of microbial pipeline corrosion in the petroleum industry Summer, Sulfur chemistry in bacterial leaching of pyrite. At this point, the acidophiles can decrease the pH further, creating an inhospitable environment for the acid-intolerant neutrophiles, and reducing the overall microbial diversity of the ARD sites, which is generally reported to be low Baker and Banfield, The detailed description set forth below in connection with the appended drawings is intended as a description of various embodiments of the present invention and is not intended to represent the only embodiments contemplated by the inventor.
