Development of Mineral Processing Flowsheet for Hematite Benefication in Yezhugou, Liaoning, China

Abstract:

A lager amount of iron ore is to be exploited in Yezhugou region, Liaoning Province. Analysis indicated that the main valuable mineral was fine-grained hematite and the total iron content was 28.22%. A process flowsheet of gravity concentrtion - high intensity magnetic separartion – reverse flotation was established, and operating conditions of each operation were also determined through batch tests. In closed-circut tests under the same operation conditions, the following results were obtained: iron content of the concentrate 64.95%, concentrate recovery 81.04%, and iron content of the tailings 8.26%.
