PERFORMANCE OF THE THICKENING PROCESS IN ERMA REKA CONCENTRATOR

摘要

There is no question that the entrainment of finely divided air in thickener feeds can cause significant problems in a thickener's operation, especially in mineral processing. This is particularly the case with thickening of flotation concentrates. The accumulation of froth on the surface of thickeners is a common problem - air bubbles attached to mineral particles are difficult to remove and a high solids carry-over into the thickener overflow can lead to a direct loss of mineral product. The formation of very stable deleterious froth in the dewatering circuit is a problem that may occur in many plants, resulting in down-time, low quality and grade of final product and considerable expenses.
