    The value of the free copper gold and silver in a copper concentrates for a copper smelter is depending on the recovery rate LME copper price and LMBA gold and silver price. In this example the recovery rate for a copper smelter is 98.0 . The value of free gold and silver is normally greater than the value of the free metal for copper.

    Smeltingan overview ScienceDirect Topics

    Matte smelting oxidizes most but not all of the Fe and S in its input concentrates. Total oxidation of Fe and S would produce molten Cu but would also result in large Cu 2 O losses in slag. The expense of reducing this Cu 2 O and settling the resulting copper almost always overwhelms the advantage of direct-to-copper smelting.
