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，钾碱的静电分离包括使钾碱矿石通过电场以基于其电荷分离不同组分。钾碱的静电分离具有许多潜在的益处 **，包括：减少或消除尾矿和/或盐水对环境的影响;降低能耗;** 降低水消耗;减少维护和腐蚀;降低生产成本;以及增加 ** 产能。然而，在北美，由于钾碱原料的 ** 组成，静电分离的效率受到限制。本研究项目将调查 ** 原料和纯钾肥饲料的静电分离，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理和面临的挑战。此外，本项目还将研究一种干法去除杂质的技术 **，特别是粘土材料。该项目的成功完成将有助于开发一种更可持续和更经济的钾矿石加工技术。
