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.

Process for treatment of volcanic igneous rocks to recover gold .

The recovery of gold, silver and platinum group metals from volcanic cinders containing iron is achieved by mixing the cinders with a suitable flux, and metallic copper, and smelting the mixture at a sufficiently high temperature to produce a molten mass of metal containing iron and copper, and a molten slag. The molten slag.
