Abstract
The invention relates to the technical field of hydrometallurgy, in particular to a method for efficiently removing iron from a leached liquid of a cobalt intermediate product.
Description
Technical Field
The invention relates to the technical field of cobalt hydrometallurgy, in particular to a method for continuously removing iron from a leached liquid of a cobalt intermediate product.
Background
Cobalt is an important raw material for manufacturing high-temperature, hard and magnetic alloys and cobalt-containing compounds, and is widely applied to the fields of aerospace, electrical and mechanical products, chemical industry, ceramics, battery industry and the like. But the cobalt resource is deficient in China, the reserves are small, and the ore taste is low. Therefore, the method has important significance for recycling the waste secondary battery, the cobalt-containing alloy, the waste catalyst, the smelting cobalt slag and other cobalt-containing secondary resources. At present, the cobalt-containing resource treatment is mainly carried out by a wet method, sulfuric acid is generally adopted for dissolving, and impurities such as iron, copper, nickel, manganese and the like also enter the solution in the cobalt dissolving process. Because iron is more reactive than other impurity metals, it is more difficult to purify it from solution.
There are four common iron removal methods in hydrometallurgy: hematite process, goethite process, astragate process and neutralization hydrolysis process. The jarosite method is relatively simple, the investment is low, the iron-removed slag is easy to filter, but the slag quantity is large, the stability of the jarosite slag is poor, and heavy metals in the jarosite slag can be continuously dissolved out under the natural stacking condition to pollute underground water and soil. The goethite method has the advantages that although the amount of slag generated in the use of secondary resources is small, the applicability to materials is strong, slag is easy to filter, and the removal effect on iron, arsenic and fluorine is good, the industrial control of process conditions is difficult; the hematite method has small slag amount, good slag filtering performance and higher iron content in the slag, can be used as a smelting raw material, but has high investment cost, large consumption of steam and sulfuric acid and overhigh energy consumption. The neutralization hydrolysis method has simple process and convenient operation, but amorphous ferric hydroxide fine particles are easily generated, the filtering performance is poor, and a large amount of other valuable metals can be adsorbed in the hydrolysis precipitation process, so that the valuable metals in the solution are lost.
Chinese patent CN 112575202A discloses a method for purifying nickel cobalt solution and recovering iron, which comprises adding an iron remover into the nickel cobalt solution to obtain iron slag and purified nickel cobalt solution, adding a regenerant into the iron slag to obtain the iron slag and the iron remover after being treated by the regenerant, and pyrolyzing the iron slag after being treated by the regenerant at 600 ℃ to obtain iron-containing oxide. The method only aims at the solution with less impurity content, and the method has the disadvantages of difficult filtration, large iron slag amount, high temperature, great consumption and unsuitability for industrial production.

(3) stirring for 30-60min, adding 98% concentrated sulfuric acid, adjusting pH to 1.2-1.5, adding hydrogen peroxide for leaching after the pH is stable, and maintaining the pH at 1.2-1.5 with acid supplementation;
