    Tailing Ponds Case Study

    • 708 Words
    • 3 Pages

    Tailing ponds are one of the greatest environmental challenges that the Oil Sands Industries of Alberta and other locations in the world face today. Tailing Ponds can be described as large “dump holes” in which the industry exposes of all the waste materials obtained from the refinement of Bitumen - a raw material which can be processed into oil. Tailing Ponds include many different types of waste materials such as water, fine silts, residual bitumen, salts and soluble organic compounds. They also include solvents that are added to the oil sands during the separation process. After the oil has been extracted from the sand the residue is dumped into the tailings and quickly settles to the very bottom. A layer on top of the hardened sand is a mixture of clay and tailing called fine tailing. This mixture of clay and water is highly unstable in the environment as it takes many years to settle and solidify, even after many years the texture of this mixture may be that of yogurt. it may take as long as or even more than 30 years for a tailing pond to fully be reclaimed. The main reason why I chose this ecological issue of tailing ponds is because as a Canadian citizen who lives in Alberta, Fort McMurray - a city which has often been labeled the least environmentally…

    scar they leave on the location of the mining. Tailing ponds are large “dump holes” in which the industry exposes of all the waste materials obtained from the refinement of Bitumen. These huge holes are made up of natural materials including water, fine silts, residual bitumen, salts and soluble organic compounds. They also include solvents that are added to the oil sands during the separation process. After the oil has been extracted from the sand the residue is dumped into the tailings and…

    As shown before Environment Canada was charging Syncrude with offences against the Migratory Birds Convention Act and Alberta Environment was charging Syncrude with offences against the Environmental Protection and Enhancement Act (Fluker, 2011). The judge that proceeded over trial was Judge Tjosvold from St. Albert (R. v. Syncrude Canada Ltd.). Syncrude’s defense against both charges laid against them is the following “It has established that it used due diligence to avoid the contamination of…

    inflammatory diseases. In literature, many works have been done in separation and quantification of aspirin and its derivative (salicylic acid) in combinations with drugs like caffeine in tablets using HPLC techniques. However, this work aims at confirming the presence and quantification of aspirin in an unknown sample (tablet) using HPLC separation technique. This was achieved by the preparation of spiked solutions of standard crystalline aspirin sample which was used as a reference point in…

    Acid Mine Drainage Prevention 1. Surface water dispersion The purpose of this action is minimizing water in contact with the potential acid material. The method is easy to apply but need to be careful in diverting the water. 2. Soil compaction The purpose of this step is to reduce the soil permeability. It means reducing the hydraulic conductivity and diffusion of oxygen. This action will reduce the water penetrate the tailing and sulfide metal oxidation. 3. Dry covers The purpose of this…

    Interpretation Acid-mine drainage occurs when sulfide-bearing waste rock and tailings come in contact with waters containing dissolved oxygen. The resulting oxidation reactions release associated metals and acidity, which may impact the biological community and significantly lower the pH of downstream waterways (Army, 2010). Released metals that are transported downstream may be removed from solution through precipitation of and sorption onto iron and manganese hydroxides. Attenuation of metals…
