一、前言多年来人们为了强化分选过程,常常将不同的场组合起来。例如,在离心磁选中,应用了离心场-磁场组合,在磁流体静力分选中应用了重力场-磁场组合,在磁流体动力分选中应用了重力场-磁场-电场组合,在粒浮中应用了化学场-重力场组合,在热浮选中应用了热场-化学场组合……。
I. Preface For many years, people often combined different fields in order to strengthen the sorting process. For example, in centrifugal magnetic separation, a centrifugal field-magnetic field combination is applied, a gravity field-magnetic field combination is applied in the hydrostatic separation, a gravity field-a magnetic field-electric field combination is used in the magnetic fluid power separation, The chemical field-gravity field combination is applied, and the thermal field-chemical field combination is applied in the thermal flotation.
