Embodiment 1

[0035] Sodium dodecylsulfonate was dissolved in a solvent at a temperature of 30°C to obtain a sulfonate solution; N,N-dimethylethanolamine and solvent were added to the obtained sulfonate solution, and after 1 hour of reaction, The obtained polymer is a novel zinc liquid purifying agent. Wherein, the mass of the dissolved sodium dodecylsulfonate solvent is 70% of the total amount of solvent added, adding sodium dodecylsulfonate accounts for 40% of the total mass, adding N,N-dimethylethanolamine accounts for the total 0.05% by mass.

[0036] In the new liquid purified by the purifying agent, the content of metal impurity ions is all below 0.5mg / L, and the content of metal cobalt after cobalt slag pickling can reach up to 10%.

Embodiment 2

[0038] Sodium dodecylsulfonate was dissolved in a solvent at a temperature of 40°C to obtain a sulfonate solution; N,N-dimethylethanolamine and solvent were added to the obtained sulfonate solution, and after 1 hour of reaction, The obtained polymer is a novel zinc liquid purifying agent. Wherein, the mass of the dissolved sodium dodecyl sulfonate solvent is 80% of the total amount of solvent added, adding sodium dodecyl sulfonate accounts for 50% of the total mass, adding N,N-dimethylethanolamine accounts for the total 0.1% of mass.

[0039] In the new liquid purified by the purifying agent, the content of cobalt and cadmium impurity ions is all below 0.5mg / L, and the content of metallic cobalt after cobalt slag pickling can reach up to 18%.

Embodiment 3

[0041] Dissolve sodium dodecylsulfonate in a solvent at a temperature of 50°C to obtain a sulfonate solution; add N,N-dimethylethanolamine and solvent to the obtained sulfonate solution, and wait for 1.5 hours to react , the resulting polymer is a new type of zinc liquid purifying agent. Wherein, the mass of the dissolved sodium dodecyl sulfonate solvent is 85% of the total solvent added, 70% of the total mass is added with sodium dodecyl sulfonate, and 70% of the total mass is added with N,N-dimethylethanolamine. 0.1% of mass.

[0042] In the new liquid purified by the purifying agent, the content of metal impurity ions is all below 0.5 mg / L, and the content of metal cobalt after cobalt slag pickling can reach up to 15%.

Abstract

The invention discloses a preparation method of a zinc liquid cleaning agent. The preparation method comprises the following steps that (1) sulfonate is dissolved into a solvent to obtain a sulfonate solution; and (2) organic amine and a solvent are added into the sulfonate solution, and the cleaning agent obtained after reacting is carried out, wherein the sulfonate is selected from one or more of alkane sulfonate, sulfamate and arylsulphonate, the organic amine is selected from one or more of N,N-dimethylethanolamine, polyethyleneimine, 1,2-dimethylpropylamine, 1,5-dimethylhexylamine or N,N-diethyl ethylene diamine. The zinc liquid cleaning agent has the beneficial effects of being simple in preparing method, short in preparing time, low temperature needed by preparation, high in impurity removal capacity and the like.

Description

technical field [0001] The invention relates to the technical field of mineral production and comprehensive utilization, in particular to a preparation method of a novel zinc liquid purifying agent. Background technique [0002] The process of zinc hydrometallurgy can be divided into five stages: roasting, leaching, purification, electrowinning and melting and casting. It is to dissolve and leach zinc roasted ore with dilute sulfuric acid solvent to obtain zinc sulfate solution. After purification, zinc is removed from the solution by electrowinning. extracted from. At present, zinc hydrometallurgy has the advantages of large production scale, low energy consumption, better working conditions, and easy mechanization and automation, and is dominant in the industry. 80% to 85% of the total zinc production comes from zinc hydrometallurgy. [0003] However, in the process of dissolving and leaching zinc roasted ore with dilute sulfuric acid solution, other impurities, such as c...
