Desliming | SpringerLink
Desliming is the process in which ultrafine particles are moved from ore by sieving, ore washing, and grading. In beneficiation, the removed microfine particles are called slime, which is an interference factor during beneficiation and directly affects separation efficiency and beneficiation reagent consumption. The purpose of desliming …
