The flotation process is used for the separation of a large range of sulfides, carbonates and oxides prior to further refinement. Phosphates and coal are also upgraded (purified) by flotation technology. "Grade-recovery curves" are tools in weighing the trade-off of producing a high grade of concentrate vs cost.

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.
