Problems solved by technology

[0002]The deoxidation of copper solution in the traditional way is to sprinkle deoxidizers into the copper solution, but because the copper solution is in a boiling state, it is difficult for these deoxidizers to enter the copper solution Therefore, only the upper part of the copper solution can be fully deoxidized, and the lower part is not fully deoxidized, or even basically cannot be deoxidized, resulting in the copper purity not meeting the requirements.

Embodiment Construction

[0013] Below in conjunction with specific embodiment, the present invention is described in detail as follows:

[0014] Concrete implementation of the present invention: this copper solution deoxidation method comprises the steps:

[0015] ①. Prepare the deoxidizer mixture. The composition of the deoxidizer mixture includes: Mn, Mg, Cu-P alloy, wherein the weight ratio of Mn relative to the copper solution is 0.300-0.600%, and the weight ratio of Mg relative to the copper solution is 0.005-0.015%, the weight ratio of Cu-P alloy to copper solution is 0.010-0.050%;

[0016] ②. Wrap the deoxidizer mixture prepared in ① with copper tape to form several deoxidizer bags;

[0017] ③. Put the deoxidizer package wrapped in ② into the copper solution, press these deoxidizer packages into the bottom of the copper solution and stir, so that the deoxidation process starts from the bottom of the copper solution.

[0018] A preferred solution: the weight ratio of Mn to copper s...

Abstract

The invention discloses a method for deoxidizing a copper solution, comprising the following steps of: firstly, preparing a deoxidizing agent mixture, wherein the deoxidizing agent mixture comprises Mn, Mg and a Cu-P alloy, the weight ratio of the Mn relative to the copper solution is 0.300-0.600 percent, the weight ratio of the Mg relative to the copper solution is 0.005-0.015 percent and the weight ratio of the Cu-P alloy relative to the copper solution is 0.010-0.050 percent; secondly, wrapping the prepared deoxidizing agent mixture with a copper belt to form deoxidizing agent bags; and finally, placing the deoxidizing agent bags into the copper solution, pressing the deoxidizing agent bags into the bottom and stirring. The deoxidizing agent adopted by the invention is a precipitation deoxidizing agent; the precipitation and deoxidization processes can be carried out in the full copper solution; remarkable deoxidizing effect can be achieved; a gaseous or solid state product is formed to facilitate the separation from the copper solution; the components of the deoxidizing agent have little influence on the copper solution so as to ensure the purity; and the deoxidizing agent has high deoxidizing effect and is suitable for being popularized and applied.

Description

technical field [0001] The invention relates to a deoxidation method, in particular to a copper solution deoxidation method. Background technique [0002] The deoxidation of the copper solution in the traditional way is to sprinkle the deoxidizer into the copper solution, but because the copper solution is in a boiling state, it is difficult for these deoxidizers to enter the bottom of the copper solution, so only the upper copper solution can be fully deoxidized. The deoxidation of the lower part is insufficient, or even basically cannot be deoxidized, resulting in that the purity of copper cannot meet the requirements. Contents of the invention [0003] The object of the present invention is to provide a method for deoxidizing a copper solution that can deoxidize a deoxidizer from the bottom of the copper solution upwards. [0004] In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions: [0005...
