Definitions
- the invention belongs to the technical field of solid waste treatment, and in particular relates to a method for separating solid waste containing nickel and cobalt.
- the extraction methods commonly used in nickel-cobalt separation mainly use acid extractant P204, P507. These kinds of extractants are weakly acidic.
- the reaction process of this kind of extractant and nickel-cobalt element is cation exchange process, which is easy to cause in the reaction process.
- the hydrogen ion concentration of the solution increases, and the acid leaching is enhanced, thereby affecting the extraction effect. Therefore, in the use of such an acidic extractant, the acidic extractant is often saponified using an alkaline liquid such as sodium hydroxide or ammonia water, and the hydrogen ion in the hydroxyl group of the acid extractant is replaced by the basic cation.
- the saponification-free extraction and separation technology will solve the problems of ammonia nitrogen wastewater in the extraction process in the extraction and separation process, and the saponification process will be eliminated.
- the process of extraction and separation can be shortened, the operation can be simplified, and the alkali consumption can be reduced, and the cost can be saved;
- the extraction process can avoid the production of wastewater such as ammonia nitrogen, which greatly reduces the discharge of wastewater.
- a method for separating nickel cobalt from a solution comprising the steps of:
- the extractant contains an acidic extractant P507 and an alkaline extractant N235.
- the nickel-cobalt-containing solution further contains chloride ions, and the concentration of the chloride ions is 3-3.5 mol/L.
- the reagent for adjusting the pH of the solution is sodium hydroxide and/or hydrochloric acid.
- the volume ratio of the acidic extractant P507 and the alkaline extractant N235 is (1 to 9): (9 to 1).
- the volume ratio of the acidic extractant P507 and the alkaline extractant N235 is (2 to 4): (6-8).
- the diluent is further added with a diluent
- the diluent is kerosene or sulfonated kerosene
- the volume ratio of the sum of the two extractants to the diluent is 1: (2-4).
- the volume ratio of the extracting agent to the solution is (3 to 5): 1.
- the method for efficiently extracting and separating nickel and cobalt proposed by the invention adopts a non-saponification extraction method, and does not use NaOH as a saponification agent, thereby avoiding the discharge of saponification wastewater.
- the acidic extractant P507 and the alkaline extractant N235 act synergistically, and the cobalt in the acid leaching solution is effectively extracted and separated into the organic phase, thereby realizing the separation of nickel and cobalt.
- the solution treated in this embodiment is a waste liquid containing a cobalt-nickel element, and is obtained by dissolving a positive electrode material of a lithium ion battery with hydrochloric acid.
- the content of nickel is 0.9 mol/L, and the content of cobalt is 0.15 mol/L.
- the nickel-cobalt solution and the synergistic extraction extractant are used for the extraction reaction, wherein the nickel-cobalt solution is adjusted to pH 4 with sodium hydroxide, and the solution contains chlorine ions of 3 mol/L.
- the extractant is added to the solution.
- the volume ratio of P507 to N235 in the extractant is 5:5.
- the volume of the two organic extractants and the thinner kerosene is 1:2, and the volume of the extractant and the aqueous phase is 3:1.
- Cobalt mainly enters the organic phase with a distribution ratio of 2.4 (calculated as cobalt).
- Synergistic extraction coefficient distribution ratio using synergistic extractant / sum of partition coefficients of one extractant alone
- the synergistic extraction coefficient of this example was 3.42.
- the nickel-cobalt solution and the synergistic extraction extractant were used for the extraction reaction, wherein the content of nickel was 0.9 mol/L, the content of cobalt was 0.15 mol/L, and the content of chloride ion was 3.2 mol/L.
- the pH of the nickel-cobalt solution was adjusted to 4 with sodium hydroxide, the volume ratio of P507 to N235 in the extractant was 3:7, the volume of the two extractants and the volume of the kerosene with the diluent was 1:3, and the volume of the extractant and the aqueous phase. It is 4:1, and it is allowed to stand for 10 min to achieve static stratification. After the interface is clear, the lower aqueous phase is separated. The distribution ratio is 11.8.
