A copper-smelting apparatus for processing of copper concentrates to produce blister copper requiring relatively low capital cost and land area is presented. The apparatus combines batch smelting processing to produce copper matte with continuous processing to produce blister copper, and all the components of the facility are built above the ground level. The apparatus includes a batch operated smelting furnace, a transport facility for transporting molten matte, and a continuous converting furnace for continuous production of blister copper by continuously receiving and processing the matte received from the transport facility. A holding container may be provided for temporarily holding the molten matte transported by the transport facility. The matte is delivered by gravity from the transport facility or the holding container to the continuous converting furnace through a first launder. The blister copper produced in the continuous converting furnace is delivered by gravity through a specified second launder to a specified refining furnace for the production of anode copper.
