Problems solved by technology

However, there are many types of copper oxide ores, which have the characteristics of high oxidation rate and bonding rate, fine mineral particle size and uneven distribution, strong hydrophilicity, high mud content, and many associated useful components. Therefore, to a certain extent Increased the difficulty of flotation of copper oxide ore, single flotation is difficult to efficiently recover complex copper oxide ore

Embodiment 1

[0052] The oxidation rate of a copper mine in the Democratic Republic of the Congo is 87.10%. The main copper minerals are malachite, chalcocite, chrysocolla, pseudomalachite, etc. Among them, malachite accounts for 65.21% of the copper oxide, and chrysocolla and pseudomalachite account for 34.79% of the total copper oxide copper content. The gangue minerals are mainly quartz, followed by carbonate minerals and silicate minerals. The particle size of copper sulfide embedding is finer, and the particle size of copper oxide embedding is coarser. The ore slime content is relatively large, and the ore properties are complex. The main valuable element of the raw ore in this embodiment is copper, the content is 5.32%, and the sulfur content is 0.42%;

[0053] like figure 1 and figure 2 Shown, apply the present invention to process above-mentioned copper ore, the dressing and smelting combined processing method of reclaiming complex copper oxide ore comprises the following steps...

Embodiment 2

[0072] Test procedure and process parameter, medicament system are exactly the same as embodiment 1. The main valuable elements of the raw ore used in the implementation are copper, with a content of 5.19%, and a sulfur content of 0.39%.

[0073] Embodiment 1 of the present invention, embodiment 2 concrete process index see table 1 below

[0074] Table 1 embodiment of the present invention technological index

[0075]

[0076]

[0077] The results of Example 1 and Example 2 shown in Table 1 show that the flotation process for efficiently reclaiming copper oxide ore of the present invention, the raw ore copper grade in Example 1 is 5.32%, and the available yield is 1.10%. High-grade copper sulfide concentrate with a copper recovery rate of 60.12% and a copper recovery rate of 12.43%; a yield rate of 9.8%, a copper grade of 5.21% and a copper recovery rate of 9.60% ore slime; a yield rate of 10.20% and a copper grade of 28.54%, copper recovery rate of 54.73% of high-grad...

Abstract

The invention discloses a dressing and smelting combined treatment method for recycling complex copper oxide ore. The method comprises the following steps of (1) copper sulfide flotation flowsheet; (2) desliming flowsheet; (3) copper oxide flotation flowsheet; (4) magnetic separation flowsheet; and (5) hydrometallurgy of copper. According to the dressing and smelting combined treatment method forrecycling the complex copper oxide ore, the sulfur and copper oxide ore step flotation process is adopted, the inhibition of copper sulfide by sodium sulfide is reduced, and high-grade copper sulfideconcentrate is obtained; and raw ore containing about 5.30% copper can adopt the method, the recycling rate of the total copper can reach 90% or above, and obtained technical indexes are good.

Description

technical field [0001] The invention belongs to the technical field of beneficiation and smelting, and in particular relates to a combined beneficiation and smelting treatment method for recovering complex copper oxide ore. Background technique [0002] With the continuous development of the national economy, the continuous development and utilization of copper ore resources, the continuous development and utilization of easy-to-handle copper ore resources, especially the continuous reduction of easy-to-handle copper sulfide ore, copper oxide ore has gradually become an important object of development and utilization. [0003] The development and utilization of copper oxide ore is relatively difficult, and there has always been a problem of low recycling rate. The treatment of copper oxide ore has different forms of treatment methods due to the difference in its components. The treatment of copper oxide ore in industry mainly adopts flotation method. However, there are many...
