STUDY ON THE FLOTATION TECHNOLOGICAL PROCESS OF LOW-GRADE WOLLASTONITE FROM LISHU MINE

In the investigation, a flotation process of desilicating in acidic medium after removal of calcite by flotation is developed by the batch test perforn1ed according to the natures of the wollastonile ore.The process is reasonable and the reagants used have cheap price and broad source. The calcite and wollastonite concentrates from low grade wollastonite ore completely reached the Eight-Five development targets.
