The Magnetic Separation Study on Flotation Concentrate Powder of Magnesite Ore

Abstract:

Iron in magnesite concentrate powder would seriously endanger the quality of refractories. Slon-500 vertical ring pulsating and high gradient magnetic separator and CRIMM DCJB70-200 laboratory electromagnetic splint VPHGMS were used to remove iron from magnesite flotation concentrate powder produced in Haicheng region. The magnetic separation results showed that using CRIMM DCJB70-200 laboratory electromagnetic splint VPHGMS is more suitable, and the most suitable operating conditions is the background field strength 641kA / m and bar spacing 2mm, at which time the magnesite concentrate yield was 91.25%, and the Fe₂O₃ content was 0.34%.
