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...
