Patent number: 5398915Abstract: There is disclosed an apparatus for smelting copper which includes a smelting furnace, a separating furnace, a converting furnace, and launders connecting these furnaces in series. In the smelting furnace, copper concentrate is melted and oxidized to produce matte and slag. In the separating furnace, the matte is separated from the slag. In the converting furnace, the matte separated from the slag is oxidized to produce blister copper. A plurality of anode furnaces are provided for refining the blister copper produced in the converting furnace into copper of higher quality. A blister copper launder assembly, which has a main launder and a plurality of branch launders branched off from the main launder, is provided to connect the converting furnace and the anode furnaces together. A selecting device may be attached to the launder assembly for selectively bringing the main launder into fluid communication with one of the branch launders.Type: GrantFiled: October 29, 1993Date of Patent: March 21, 1995Assignee: Mitsubishi Materials CorporationInventors: Moto Goto, Nobuo Kikumoto, Osamu Iida, Hiroaki Ikoma, Shigemitsu Fukushima

Patent number: 5374298Abstract: There is disclosed a copper smelting process. At first, blister copper is produced in a blister copper-producing facility. Then, the blister copper is caused to flow through blister copper launders into one of anode furnaces, and refined into copper of higher quality in the anode furnace. In the refining operation at the anode furnace, the receiving step and the oxidizing step are carried out at least partly in an overlapping fashion.Type: GrantFiled: March 31, 1993Date of Patent: December 20, 1994Assignee: Mitsubishi Materials CorporationInventors: Moto Goto, Nobuo Kikumoto, Osamu Iida

Patent number: 5320662Abstract: There is disclosed a process for continuous copper smelting. At first, a smelting furnace, a separating furnace, a converting furnace, melt launders for connecting the smelting furnace, the separating furnace and the converting furnace in series, a plurality of anode furnaces and blister copper launders for connecting the converting furnace and the anode furnaces are provided. Then, copper concentrate is introduced in the smelting furnace, and melted and oxidized into a mixture of matte and slag. The mixture is received in the separating furnace and the matte is separated from the slag. Subsequently, the matte separated from the slag is oxidized to produce blister copper. Subsequently, the blister copper is caused to flow through the blister copper launders into one of the anode furnaces, and refined into copper of higher quality in the anode furnace. In the refining operation at the anode furnace, the receiving step and the oxidizing step are carried out at least partly in an overlapping fashion.Type: GrantFiled: May 4, 1993Date of Patent: June 14, 1994Assignee: Mitsubishi Materials CorporationInventors: Moto Goto, Nobuo Kikumoto, Osamu Iida
