Tribo-electrostatic separation of potash

点击翻译按钮获取中文摘要

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.
