Graphite ore flotation processing flow chart
The flotation method is a relatively common method for purifying minerals. Since the graphite surface is not easily wetted by water, it has good floatability and is easily separated from impurity minerals. The flotation of graphite ore is generally carried out by positive flotation followed by reverse flotation of the flotation concentrate.
