Abstract:High efficient in ironremoval of non-metallic mine,at present,ZQS-type circle high gradient magnetic separator is widely employed in the field of ironremoval of silica sand,kaolin,and feldspar etc.,especially in solar photovoltaic glass area which could meet the requirement of Fe content under 0.008,.Applied in a silica sand plant in Guangdong,0.0072, Fe2O3 content and 81.18, ironremoval rate of silica sand product could be achieved. Applied in a kaolin plant in Guangdong,0.85, Fe2O3 content and 83.6, whiteness of kaolin product could be achieved. Applied in a feldspar plant in Hebei,0.10, Fe2O3 content and 55.4, ironremoval rate of feldspar fine clay could be achieved after the treatment of high gradient magnetic separator.
