Problems solved by technology

[0003] The continuous copper smelting processes that have been put into operation include double flash method, Mitsubishi method, and double bottom blowing continuous copper smelting process, all of which are three-stage (three-step) copper smelting processes, and anode copper is produced by 4 or 5 furnaces. However, the above-mentioned continuous copper smelting process generally has problems such as high requirements for copper-containing raw materials, long process flow, self-heating of the smelting furnace, and difficulty in slagging.

Embodiment Construction

[0026] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0027] The following is based on figure 1 The basic structure of the continuous copper smelting plant 100 of the embodiment of the present invention will be described.

[0028] The continuous copper smelting equipment 100 includes a side-blowing smelting furnace 110 and at least two bottom-blowing smelting and refining furnaces.

[0029] The side blowing melting furnace 110 has a melting chamber. The side-blown smelting furnace 110 is also provided with a feeding port for feeding materials, a smelting slag outlet for discharging smelting slag, and a copper matte outlet for discharging copper matte, which communicate with the melting chamber. Copper-containing ...

Abstract

The invention provides a continuous copper smelting equipment and a two-stage continuous copper smelting process. The blowing and refining are completed in the bottom blowing blowing and refining furnace at one time, without the need for blister copper reloading, which shortens the process flow, improves operating efficiency, saves investment costs and operating costs, and reduces labor intensity. In addition, by using a combination of side-blowing smelting furnaces and at least two bottom-blowing refining furnaces, the bottom-blowing refining furnaces are alternately operated to ensure the continuous discharge of copper mattes produced from side-blowing melting furnaces, and to achieve continuous Copper smelting reduces the waiting time for furnace shutdown, improves work efficiency and reduces costs. In addition, the blowing slag and oxidized refining slag are discharged from the smoke outlet by rotating the bottom blowing blowing and refining furnace, which is beneficial to improve the slag discharge efficiency and make the slag discharge cleaner, so that higher quality anode copper can be produced.

Description
