The Northern Alberta Institute of Technology (NAIT) Centre for Oil Sands Sustainability (COSS) will work with BASF Canada Inc. to assess a new technology, a calcium based polyacrylamide (Ca-PAM), developed to eliminate the addition of gypsum to tailings treatment processes. Use of gypsum as part of the chemical treatment of fluid fine tailings has proven to have negative impacts on oil sands bitumen extraction and the quality of water release for recycling into the extraction process. The oil sands is a major contributor to the Canadian economy, with well understood impacts on the environment, particularly with regards to tailings and water quality. Tailings represent the number one liability to oil sands mining firms, with an estimated treatment cost between 5 to 10 billion dollars for existing stockpiles. Potential impacts of new products, such as Ca-PAM, present an opportunity to improve tailings treatment. The data from this research will provide BASF with insight into potential technology refinement that will help industry's efforts to effectively manage tailings while optimizing bitumen recovery. Data from this study will also help oil sands mining operations understand the full impacts of this technology on extraction processes assisting with its potential adoption. NAIT staff will deepen their knowledge of oil sands tailings treatment and its impact on the bitumen extraction process. This project will benefit Canada's environment by enabling oil sands operators to reclaim decommissioned mines faster and require less fresh water in the oil sands mining process.

北艾伯塔省技术学院（NAIT）油砂可持续发展中心（COSS）将与加拿大巴斯夫公司合作评估一种新技术，即一种基于钙的聚丙烯酰胺（CA-PAM），以消除在尾矿治疗过程中添加石膏。使用石膏作为液体细尾矿的化学处理的一部分，已证明对油砂沥青提取以及释放水质产生负面影响，以回收到提取过程中。油砂是加拿大经济的主要贡献者，对环境的影响有充分的影响，尤其是在尾矿和水质方面。尾矿代表了油砂矿业公司的第一责任，现有库存的估计治疗费用在5至100亿美元之间。新产品（例如CA-PAM）的潜在影响为改善尾矿治疗的机会提供了机会。这项研究的数据将为BASF提供对潜在技术改进的见解，这将有助于行业有效地管理尾矿的努力，同时优化沥青恢复。这项研究的数据还将有助于油砂开采操作了解该技术对提取过程的全部影响，以帮助其潜在的采用。 Nait的工作人员将加深他们对油砂尾矿治疗的了解及其对沥青提取过程的影响。该项目将通过使油砂运营商能够更快地恢复退役矿场，并在油砂开采过程中需要更少的淡水来使加拿大的环境受益。
