gradient magnetic separation (PHGMS) would greatly reduce the entrainment effect and can obviously increase the grade of the magnetic product. It is also very helpful for reducing the clogging of the matrix [27, 28]. In the present investigation, a typical Iranian low grade iron ore sample collected from Tange-zagh mine was considered.
