Concentrates are usually specific to particular smelters. Thus a lead smelter or a zinc smelter could not smelt a copper concentrate (the converse is also true). In fact any copper in a lead or zinc concentrate is generally problematic in the smelting/refining processes and would most likely incur a penalty charge (see more on penalties below).
