PTMS magnetic separation The influence of magnetic separation times and magnetic field strength on the effect of iron removal
Magnetic separation process
Generally speaking, if the impurities in quartz sand are mainly weak magnetic impurity minerals such as limonite, hematite and biotite, then it can be selected by using the magnetic field strength of wet PTMS magnetic separation above 10000GS. For those strong magnetic minerals mainly containing magnetite, the selection effect of using weak magnetic machine or medium magnetic machine will be better.
PTMS magnetic separation
In order to explore the best mineral conditions, the researchers studied the experimental conditions of quartz sand. The results show that the PTMS magnetic separation magnetic concentration times and magnetic field strength have an important influence on the effect of iron removal. As the number of magnetic selection times increases, the iron content will gradually decrease. At a certain magnetic field intensity, most of the iron can be removed.
what is magnetic separation in Kaolin?
However, when the PTMS magnetic separation magnetic field strength is increased to a certain extent, even if it increases significantly, the iron removal rate will not change much. It should be noted that when quartz sand contains more impurity minerals, it is impossible to purify quartz sand into high purity sand only by scrubbing, dredging and magnetic separation.
