Problems solved by technology

In the above method, since the clay can only play an adsorption role, the removal effect on flocs is very limited, and the separation efficiency is also very low
Moreover, the organic matter recovered by using clay has complex components. In addition to the extractant, it also contains degradation impurities, etc., and it is difficult to completely separate these substances.

Embodiment 1

[0021] The special complexing agent for copper extractant in this embodiment includes the following components in parts by weight: 1 part of silicon-containing inorganic adsorbent, 10 parts of silicon-containing organic adsorbent, 10 parts of clay, and 0.5 part of activated carbon. In this embodiment, the silicon-containing inorganic adsorbent is 1 g, the silicon-containing organic adsorbent is 10 g, the clay is 10 g, and the activated carbon is 0.5 g, wherein the silicon-containing inorganic adsorbent is white carbon black, and the silicon-containing organic adsorbent It is monosilane, the clay is a clay mixture obtained by mixing white clay and red clay in a ratio of 1:1 and then drying, and the activated carbon is plant activated carbon.

[0022] The preparation method of above-mentioned complexing agent special for copper extractant comprises the steps:

[0023] 1) After the white carbon black is pulverized, magnetically separated, screened, sulfuric acid pickled and washe...

experiment example

[0031] Taking the Lix series copper extractant system used by an enterprise for a certain period of time as the experimental object, the technical indicators of the copper extractant are as follows:

[0032] 1) After nuclear magnetic detection, the content of organic phase components in the copper extractant system is 14.3%. The content of organic phase components refers to the content of pure copper extractant in the copper extractant system, and the remaining components in the system are diluents and degradants. after impurities.

[0033] 2) After titration detection, the content of copper loading in the original organic phase is 8.35g / L, wherein the copper loading content of the organic phase refers to the amount of copper contained in the organic phase of the extraction agent with a unit volume concentration after the copper extraction agent extracts copper. Concentration of extractable metals (g / L).

[0034] 3) The extraction and phase separation time of the copper extra...

Abstract

The invention relates to a complexing agent special for a copper extracting agent and a preparation method thereof, and belongs to the technical field of wet metallurgy of copper. The complexing agent special for the copper extracting agent comprises, by weight parts, 1-2 parts of silicon-containing inorganic adsorbents, 1-20 parts of silicon-containing organic adsorbents, 1-52 parts of clay and 0.1-0.5 part of activated carbon. The silicon-containing inorganic adsorbents are one or more of gedanite, white carbon black, smectite, allophane and vermiculite. The silicon-containing organic adsorbents are one or more of silane, polysiloxane, polysilane and silicon resin. According to the complexing agent special for the copper extracting agent, the elimination rate of flocculation dirt in the copper extracting agent reaches over 90%, the extraction phase splitting efficiency is improved over 50%, and the use cycle of the copper extracting agent is obviously prolonged.

Description

technical field [0001] The invention relates to a special complexing agent for copper extractant and a preparation method thereof, belonging to the technical field of copper hydrometallurgy. Background technique [0002] Copper is a metal that is widely used, especially in electronic products, and it also produces a large amount of copper-containing electronic scrap and garbage. With the increasing requirements for environmental protection, copper recycling and refining has gradually become one of the main sources of raw copper. Among copper recovery and refining methods, hydrometallurgy has a wide range of applications due to its simple process, and the most widely used hydrometallurgy method is copper extractant extraction. Copper extractant extraction method is popular in the field of copper recovery and refining because of its simple operation and high efficiency. [0003] However, when the copper extractant is used to extract copper, the copper extractant will gradual...
