    The remaining molten material in the bottom of the furnace is called the matte. It is a mixture of copper sulfides and iron sulfides and contains about 60% copper by weight. 7 The molten matte is drawn from the furnace and poured into a second furnace called a converter. In some cases, the production costs may increase significantly.
