Abstract
Our previous research on centrifugal high gradient magnetic separation (cHGMS) has fully confirmed its effectiveness to improve the separation selectivity of HGMS process, but they were confined in pilot-scale investigations. In this work, the first full-scale CenMag-300 cHGMS separator was used to clean a primary ilmenite concentrate, which was produced from a pulsating HGMS (PHGMS) roughing process. The separation results demonstrated that it was able to improve the TiO2 grade from 15.25 % in feed to 32.49 % in concentrate at TiO2 recovery reaching 81.07 %, which is much superior to that of cyclic SLon-100 PHGMS separator. The outcome from this investigation confirmed the feasibility of cHGMS technology for industrial operation.
期刊介绍：
The purpose of the journal is to provide for the rapid publication of topical papers featuring the latest developments in the allied fields of mineral processing and extractive metallurgy. Its wide ranging coverage of research and practical (operating) topics includes physical separation methods, such as comminution, flotation concentration and dewatering, chemical methods such as bio-, hydro-, and electro-metallurgy, analytical techniques, process control, simulation and instrumentation, and mineralogical aspects of processing. Environmental issues, particularly those pertaining to sustainable development, will also be strongly covered.
