Claims
- 1. An apparatus for smelting copper comprising:
- blister copper producing means;
- a plurality of blister copper refining furnaces for refining blister copper into copper of higher quality; and
- blister copper launder means connecting said blister copper producing means and said blister copper refining furnaces.
- 2. An apparatus for smelting copper as recited in claim 1, wherein said blister copper launder means includes a main launder having one end connected to said blister copper producing means and a plurality of branch launders each having one end connected to the other end of said main launder and the other end connected to one of said plurality of blister copper refining furnaces.
- 3. An apparatus for smelting copper as recited in claim 2, further comprising a selecting device attached to said blister copper launder means for selectively bringing said main launder into fluid communication with one of said branch launders.
- 4. An apparatus for smelting copper as recited in claim 1, wherein at least one of said plurality of blister copper refining furnaces includes a furnace body having a shell portion and a pair of end plates mounted on opposite ends thereof, said furnace body being supported rotatably about an axis thereof with said axis being arranged horizontally, said shell portion of said furnace body having a circumferentially extending opening for receiving the blister copper; and wherein said blister copper launder means includes an end portion disposed at said opening of said furnace body.
- 5. An apparatus for smelting copper as recited in claim 4, wherein at least one of said plurality of blister copper refining furnaces further includes an exhaust duct formed so as to provide a hood over said opening of said furnace body in relation to a prescribed rotational range of said furnace body, whereby exhaust gas is exhausted through said opening.
- 6. An apparatus for smelting copper as recited in claim 5, wherein said end portion of said blister copper launder means located above said opening of said furnace body is provided with a water-cooling jacket.
- 7. An apparatus for smelting copper as recited in claim 3, wherein said plurality of blister copper refining furnaces are disposed parallel to one another with one end of each anode furnace being directed toward said blister copper producing means while shell portions of adjacent blister copper refining furnaces are opposed to each other.
- 8. An apparatus for smelting copper as recited in claim 1, wherein said plurality of blister copper refining furnaces are arranged in parallel.
