项目摘要
With increasing global awareness for the needs of sustainable development, exploitation of natural resources respecting the environmental and societal impacts has become the centerpiece of policy makers around the world. Hydrometallurgy uses water-based chemistry and engineering for metal recovery from natural mineral resources and mining wastes by employing a variety of chemical conditions within a wide range of temperatures and pressures. The present research programme constitutes an on-going effort that focuses on improving the efficiency of water recovery, recycling and quality monitoring in the natural resource industry. It continues theoretical advances backed by experimental measurements in sustainable hydrometallurgy. The proposed research aims at discovering new energy efficiencies for process water purification for metallurgical plant reuse by forward osmosis and freeze-thaw crystallization. By using soluble inorganic electrolytes recoverable by eutectic freeze crystallization technology the energy cost of forward osmosis can be further minimised. We will also investigate the fundamentals of ice growth in multicomponent electrolyte systems using advanced techniques to improve the quality of produced ice. Freeze-thaw crystallization is relying on the natural freezing of the surface waters that occurs naturally in Canadian winters. An engineered process can separate clean water from contaminated process solutions, tailings waters and effluent streams. The underlying hypothesis is that these processes can achieve better water separation efficiency in terms of energy requirements and quality of water produced than current technology. An additional project aims at furthering the development of robust sensors for monitoring redox water chemistry in high temperature process waters using advanced signal processing techniques. Overall, the proposed research program aims at the hydrometallurgy of efficient net water usage. The program will train three doctoral, one post doctoral and fifteen undergraduate/summer students in sophisticated techniques on water chemistry and sensors on processes encountered in the minerals industry under complex experimental conditions. This work contributes to the Canadian economy by investigating novel ideas in the minerals sector that renders metal producers more competitive in the global markets to satisfy the world demand for metals produced in an environmentally respectful, sustainable and sound manner.**
随着全球对可持续发展需求的认识不断提高,尊重环境和社会影响的自然资源开发已成为世界各地政策制定者的核心。湿法冶金使用水基化学和工程,通过在广泛的温度和压力范围内采用各种化学条件,从天然矿物资源和采矿废物中回收金属。 目前的研究方案是一项持续的努力,重点是提高自然资源工业中水回收、再循环和质量监测的效率。 它继续在可持续湿法冶金的实验测量支持的理论进步。拟议的研究旨在发现新的能源效率的工艺水净化冶金厂再利用的正渗透和冻融结晶。 通过使用可通过共晶冷冻结晶技术回收的可溶性无机电解质,可以进一步最小化正渗透的能量成本。我们还将研究冰生长的多组分电解质系统的基本原理,使用先进的技术,以提高生产的冰的质量。 冻融结晶依赖于加拿大冬季自然发生的地表沃茨的自然冻结。工程工艺可以将清洁水从受污染的工艺溶液、尾矿沃茨和流出物流中分离出来。潜在的假设是,这些过程可以实现更好的水分离效率在能源需求和水的质量比目前的技术。另一个项目旨在利用先进的信号处理技术,进一步开发用于监测高温工艺沃茨中氧化还原水化学的可靠传感器。总的来说,拟议的研究计划的目的是有效的净用水的湿法冶金。该计划将培养三名博士,一名博士后和十五名本科生/暑期学生在复杂的实验条件下在矿物工业中遇到的水化学和传感器过程的复杂技术。 这项工作通过调查矿产部门的新想法,使金属生产商在全球市场上更具竞争力,以满足世界对以环保,可持续和健全的方式生产的金属的需求,从而为加拿大经济做出贡献。
