Electrostatic separation of potash in theory consists of passing potash ore through an electric field to separate**different components based on their charge. Electrostatic separation of potash has many potential benefits**including: reduced or eliminated environmental impact of tailings and/or brine; reduced energy consumption;**reduced water consumption; reduced maintenance and corrosion; reduced cost of production; and an increase in**capacity. However, the efficiency of electrostatic separation in North America has been limited due to the**composition of the raw potash materials. This research project will investigate the electrostatic separation of**raw and pure potash feeds to better understand the fundamental mechanism and challenges facing successful**application of electrostatic separation in Saskatchewan. Additionally, this project will investigate a technology**for the dry removal of impurities, specifically, clay materials. Successful completion of the project will**contribute to the development of a technology for processing potash ore that is more sustainable and more**economical.

理论上，钾盐的静电分离包括使钾矿石通过电场，根据电荷分离**不同的成分。钾盐的静电分离具有许多潜在的好处**包括：减少或消除尾矿和/或盐水对环境的影响；减少能源消耗；**减少水消耗；减少维护和腐蚀；降低生产成本；以及**容量的增加。然而，由于钾肥原料的成分，北美静电分离的效率受到限制。该研究项目将研究**原料和纯钾原料的静电分离，以更好地了解静电分离在萨斯喀彻温省成功应用**的基本机制和面临的挑战。此外，该项目将研究干法去除杂质（特别是粘土材料）的技术**。该项目的成功完成将**有助于开发更可持续、更**经济的钾矿石加工技术。
