Effects of Chemical Additives on Rheological Properties

2021-11-25  Grinding is an indispensable step in mineral processing to reduce particles’ size and liberate minerals before they are subjected to further separation processes. Grinding is charac-terized by high energy consumption and low energy efficiency (~ 1%) (Cheng et al. 2019; Liu et al. 1989; Napier-Munn 2015).
