Abstract: All magnetic media should remoued from whole device in former industrial tests on magnetic media of high-gradient magnetic separator, meanwhile two devices were operated in parallel for comparison.It is difficult to ensure the consistency of the other working conditions for the magnetic separator by this method, causing large amount of time, labor and material consumption.So, a new approach for the industrial tests on magnetic media of high gradient magnetic separator is proposed.In this process, numerous different magnetic media modules are installed in one magnetic separator.Through comparing with absorption capacity and residual volume of different magnetic media modules before and after minerals unloading, the advantage and disadvantage of different magnetic media can be determined.Then, the recovery rate of a magnetic separator by using the same kind of magnetic media can be predicted.The practical application in Meishan concentrator has proved its feasibility.
