| Abstract: | In this paper, a cyclic pulsating high gradient magnetic separator of laboratory size and its principle are described. The effects of pulsating stroke and frequency on separation response are discussed. Binary Mineral system of wolframite- quartz and natural hematite ore are used in this study. It is demonstrated that pulsation can effectively liberate the non-magnetic particles trapped in the matrix and consequently greatly enhance the beneficiation ratio of magnetic concentrate. The process of particle built up in pulsating high gradient magnetic separation is proposed based on the theoretical and experimental studies. |
