In order to develop the pulsating high–gradient magnetic separation technology, a laboratory pulsating high–gradient magnetic separator (PHGMS) has been manufactured.. Experiments on its separation performance were carried out. The results show that PHGMS can significantly increase the grade of the magnetic product and it can eliminate the matrix clogging. The characteristic curve of the pulsating fluid was measured and a formula for estimating the grade of the magnetic product from PHGMS was established.
