磨矿—分级、浮选、固液分离等过程中的矿浆就是一种微粒流体。针对流体复杂的粘度和屈服应力，讨论了新的控制策略。微粒流体受非牛顿流变学支配（即剪切稀化、剪切稠化、剪切屈服应力和抗压屈服强度）。流变学控制策略取决于矿粒与矿粒之间的基本作用力，加上其它足够的信息，可以有效地利用这些复杂的剪切性质。探索了在最终精矿和尾矿的处理中矿物微粒流体保持较高固体重量百分比的优越性，并提出了相应的控制策略。
Grinding ore - grading, flotation, solid-liquid separation and other processes in the pulp is a particulate fluid. Aiming at the complex viscosity and yield stress of fluid, a new control strategy is discussed. Particulate fluids are governed by non-Newtonian rheology (ie shear thinning, shear thickening, shear yield stress and compressive yield strength). The rheology control strategy depends on the basic forces between the ore particles and the mineral particles, together with other enough information, to effectively utilize these complex shear properties. Explored the superiority of the mineral particulate fluid in maintaining the high solid weight percentages in the final concentrate and tailings treatment and proposed corresponding control strategies.
