Hatch, a global multidisciplinary engineering company, provides services to a wide range of industries including the mining, mineral processing, and metals industry. The GDP contribution of this sector in Canada was about $52.6 billion in 2012. Liquid-liquid extraction is an important unit operation in the mining and mineral processing industry. In liquid-liquid extraction, the transfer of a solute (metal) takes place by contacting two immiscible liquids, usually water and an organic solvent. The metal is transferred from the aqueous phase to the organic phase by a means of an extractant. Disadvantages of conventional technologies in the metal extraction industry include the use of mechanical agitators that generate a wide range of droplet size, increase in residence time, large inventories of expensive organic solvent, and large settler tanks. Furthermore, the use of large volumes of organic solvents increase plant footprint, decrease plant safety, increase environmental impact and, due to environmental regulations, it is necessary to recover the organic solvent, which introduces additional costs to the process. In this proposed NSERC Applied Research Development Grant, Sheridan College and Hatch Ltd. are seeking to solve these problems by designing and constructing a custom-made mixer and settler to improve mixing performance and minimize separation time. By using this novel technology, higher specific treatment rates are expected resulting in significant reductions in plant footprint and organic inventories. Furthermore, this proposed project will result in a novel technology with lower capital and operational costs and improved safety. Sheridan will benefit by engaging students from the Faculty of Applied Science and Technology's Chemical Engineering Department and Mechanical Engineering Department to solve real industrial engineering problems and by creating employment-ready graduates.

全球多学科工程公司Hatch为包括采矿，矿产加工和金属行业在内的广泛行业提供服务。该行业在加拿大的GDP贡献在2012年约为526亿加元。液体液体提取是采矿和矿产加工行业的重要单位运营。在液体液体提取中，通过接触两个不混溶的液体，通常是水和一个有机溶剂来进行溶质（金属）的转移。金属通过萃取剂的方法从水相传递到有机相。金属提取行业中传统技术的缺点包括使用机械搅拌器，这些机械搅拌器会产生各种各样的液滴尺寸，增加停留时间，大量昂贵的有机溶剂的库存和大型的储罐。此外，大量有机溶剂的使用增加了植物的占地面积，降低了植物安全性，增加了环境影响，并且由于环境法规，有必要恢复有机溶剂，从而引入了该过程的额外成本。 在拟议的NSERC应用研究开发赠款中，谢里丹学院和Hatch Ltd.试图通过设计和构建定制的混音器和定居者来解决这些问题，以提高混合性能并最大程度地减少分离时间。通过使用这项新技术，预计更高的特定治疗率将大大降低植物足迹和有机库存。此外，这个提议的项目将导致一项新型技术，其资本和运营成本较低并提高了安全性。 Sheridan将通过与应用科学技术学院化学工程系和机械工程系的学生吸引学生来解决真正的工业工程问题并创建有关就业就业毕业生。
