Embodiment Construction

[0030] Describe the present invention in detail below in conjunction with accompanying drawing and embodiment:

[0031] A kind of multi-metal recovery and treatment process of germanium production waste liquid, the specific technical scheme is:

[0032] A extraction of gallium, by the way recovery of germanium process section

[0033] (a1) use kerosene as the diluent of extractant A, make it into the extraction organic phase containing extractant A30%, directly extract gallium from the germanium production waste liquid containing complex multiple metal ions, the organic phase is compared with the extraction phase of the aqueous phase Ratio = 1:4~6, extraction and mixing time is 5 minutes to 6 minutes, settling time is 10 minutes to 15 minutes, extraction temperature is 35°C to 40°C, and the number of extraction stages is four-stage countercurrent extraction;

[0034] (a2) The gallium-rich organic phase is washed with tap water, and the washing water is returned to the germani...

Abstract

The invention relates to a multi-metal recovery processing technique of waste liquid generated in a germanium producing process, belonging to the technical field of non-ferrous metal wet method metallurgy. The multi-metal recovery processing technique comprises the following steps: extracting germanium from the waste liquid generated in the germanium producing process by an extractant A and a kerose diluent, washing, carrying out back-extraction, removing impurities, purifying, depositing the germanium and electrolyzing to obtain the metal germanium with the purity of 99.99%; firstly extracting iron and partial impurities from the residual waste liquid after extracting the germanium by an extractant B and the kerose diluent, and extracting indium from the residual waste liquid after extracting the iron by the same organic extractant B, adjusting the pH, extracting the indium by the extractant A, carrying out the back-extraction, neutralizing, oxidizing, removing the impurities and replacing to obtain spongy indium, and then briquetting and casting to obtain 99% metal indium. The invention has the advantages of short process flow, small occupied area, few investment, fast implementation and good working conditions, solves the problems that the valuable metal in the waste acid solution can not be recovered and has higher value of the resource comprehensive utilization. Furthermore, the metal recovery rate is larger than 92%; the purity of the obtained product, metal germanium, is 99.99%, and the purity of the metal indium is 99%.

Description

technical field [0001] The invention relates to a technique for recovering polymetallics from complex solutions, which belongs to nonferrous metal hydrometallurgy technology. In more detail, the multi-metal recovery and treatment process of germanium production waste liquid. Background technique [0002] Since indium and gallium are scattered metals, the chemical symbols are In and Ga, and they are associated in aluminum, lead, zinc, tin ore or coal in a scattered state, and there are no separate minerals. It is widely distributed in various process products of various metallurgical factories, especially in the production of germanium metallurgical industries. Therefore, the waste liquid produced in the germanium production process also contains scattered metals such as indium and gallium that are expected to be recovered. Conventionally, as a treatment technology for recovering waste liquids of these metals, coagulation precipitation treatment with chemicals, co-precipita...
