Embodiment 1

[0048] A corporate copper anode pressure leaching is shown in a copper solution, and its main chemical composition is shown in Table 1.

[0049] Table 1 Raw material ingredient

[0050]

[0051] The treatment method of copper anode mud copper fluid according to the present invention is used to treat the discharge liquid, and the process flow chart is figure 1 As shown, including the following steps:

[0052] (1) Add 2 L of volume copper solution to a swirling electrolytic storage tank, and disposes the electric heating sleeve target temperature of 25 ° C, opening the magnetic drive cycle pump for electrolyte circulation, and adjusts the circulating flow rate of the electrolyte to 600 l / h. When the solution is cycled, there is no obvious bubble, turn on the power, control the current density bit 1500A / m. 2 Perform the first electrolysis. When the concentration of the orecty is reduced to 0.08 g / L to stop the electrolysis, the catholysis residue in the cathode collector is r...

Embodiment 2

[0062] A high-mixed copper fluid is shown in Table 4.

[0063] Table 4 Raw material ingredient

[0064]

[0065] The disconnect solution is treated with the treatment method of the copper anode mud copper fluid of the present invention, including the steps of:

[0066] (1) Add 2 L of volume copper solution to a swirling electrolytic storage tank, and provide an electric heating sleeve target temperature of 25 ° C to turn on the magnetic drive cycle pump for electrolyte cycle, and adjust the circulating flow rate of the circulating flowmeter adjusted electrolyte. 600L / h. When the solution is cycled, there is no obvious bubble, turn on the power supply, control the current density 1600A / m. 2 Perform the first electrolysis. When the concentration of the orecty is reduced to about 0.05 g / L to stop the electrolysis, the catholysis residue in the cathode collector is removed, and the recovery rate of the entire process of 199.1%, and the content of the content of the lysyl tellu...

Abstract

The invention discloses a method for treating copper anode slime copper separation liquid: adding copper anode slime copper separation liquid into a swirling flow electrolysis device to carry out the first stage of swirling flow electrolysis, and taking out the first stage cathode product after reaching the electrolysis end point; continuing to carry out In the second stage of swirl electrolysis, take out the second stage cathode product after reaching the end of electrolysis; continue to carry out the third stage of swirl electrolysis, take out the third stage cathode product after reaching the end of electrolysis and collect the electrolysis solution. In the present invention, the copper anode slime copper liquid is reclaimed by swirl electrolysis cascades, and active copper powder is generated at the cathode through the first section of swirl electrolysis with high current density, and the tellurium in the solution is directly replaced to obtain copper telluride slag, and the tellurium is obtained High-efficiency enrichment, while avoiding the influence of tellurium on the subsequent copper electrolysis; the cathode copper product obtained through the second stage of swirl electrolysis meets the specifications of the national standard cathode copper; through the third stage of swirl electrolysis, the arsenic is effectively solidified in the In the black copper slag, the deep recovery of copper is realized, and the impurity removal and recycling of the solution are realized.

Description

Technical field [0001] The present invention is in hydrometallurgy, and in particular relates to a method for processing anode sludge copper fraction copper solution. Background technique [0002] Copper anode mud rich Se, Cu, Pb, As, Au, Ag, Te and other elements, are an important source of precious metal recovery. Typically gold is recovered from the anode slime, which to be pre-leached to remove copper silver, copper anode sludge according to the chemical composition, phase composition and associated metal content, may be employed acid pressure leaching, oxidative leaching, alkali leaching oxygen pressure chloride leaching or the like anode slime leaching of copper was obtained points. However, in addition to copper arsenic, tellurium, also points into the liquid copper, especially copper electrolytic solution, even when it contains traces of tellurium, also have an adverse effect on the quality of electroless copper, the copper must be removed liquid fraction tellurium. The r...
