Matte with a copper grade of 60 to 65% is sent from the flash furnace to the converter in order to increase its purity. With oxygen blown into the converter, the sulfur content is removed as a gas and iron is removed into silicon (main component of gold ore). As a result, a portion of the matte becomes slag. Thus, crude copper.
