If a blast furnace is used, this copper is charged to a converter, where the purity is increased to about 80 to 90 percent, and then to a reverberatory furnace, where copper of about 99 percent purity is achieved. The final step is known as fire-refining. In these pyrometallurgical processes, flux is added to the copper and air is blown upward
