Definitions

  • the present invention relates to a method for purifying an aqueous cobalt chloride solution.
  • Cobalt is a rare metal and a valuable metal used as an alloy material. Further, as an application other than the alloy, cobalt is also used as a battery electrode material. For example, cobalt is also used for a positive electrode material of a lithium ion battery, which is a non-aqueous electrolyte secondary battery for vehicle use, which has been developed in recent years.
  • salts for example, cobalt salts, such as cobalt sulfate and cobalt chloride
  • the cobalt salt described above can be obtained as a by-product of the process of smelting nickel ore and the like. Specifically, wet processing is adopted for purification of impurities, and a cobalt salt is generated from a cobalt salt solution generated at that time.
  • nickel ore and the like contain a wide variety of impurities such as manganese, iron, copper, and chromium in addition to nickel and cobalt. If impurities are also contained in the cobalt salt solution, impurities may be mixed into the cobalt salt. And if the cobalt salt containing an impurity is used for manufacture of a positive electrode material, an impurity may mix in a positive electrode material.
  • the presence of impurities in the positive electrode material greatly affects the performance of the positive electrode material, that is, the battery characteristics.
  • the lithium ion battery as described above has a high capacity and a high voltage, the presence of a trace amount of impurities greatly affects the battery characteristics, so the specifications of impurities of raw materials such as cobalt salts are very strictly controlled.
  • the specifications of impurities of raw materials such as cobalt salts are very strictly controlled.
  • copper is an important impurity that greatly affects the performance of the battery, it is required to strictly control the amount of copper contained in raw materials such as cobalt salts.
  • Methods such as solvent extraction and electrolysis are known as methods for reducing impurities such as copper contained in cobalt salts. That is, if copper is removed from the cobalt salt solution by a solvent extraction method or an electrolytic method, the copper concentration in the cobalt salt solution, that is, the amount of copper contained in the cobalt salt can be reduced. However, these methods cannot reduce the lower limit concentration of copper that can be separated so much. In addition, these methods require a large-scale apparatus such as a solvent extraction apparatus such as a mixer-settler, an electrolytic cell or a power source, and thus have problems such as an increase in capital investment and a high processing cost.
  • the precipitation method is a method for separating impurities by adding a neutralizing agent, a sulfurizing agent, or the like, and is widely used for wastewater treatment of heavy metals such as copper.
  • the sulfidation method in which copper is precipitated and removed using a sulfiding agent, has very low copper sulfide solubility (water solubility: 18 ° C, 3.4 x 10 -4 g / L), and the concentration of copper in the solution. There is an advantage that can be greatly reduced.
  • harmful hydrogen sulfide gas is used as a sulfiding agent, it is necessary to ensure the safety of workers and to take environmental measures.
  • Various devices have been devised in order to control hydrogen sulfide (for example, Patent Document 1), but there is a problem that the cost of incidental equipment increases because the device configuration becomes complicated.
  • the solubility of copper hydroxide increases at a pH lower than pH 8. For this reason, the concentration of copper in the cobalt salt solution cannot be so low. Specifically, in order to prevent cobalt loss, the solubility of cobalt needs to be 100 g-Co / L or more. Since the solubility product of cobalt is 2.2 ⁇ 10 ⁇ 16 , the pH must be 6 or less. On the other hand, the solubility product of copper is 2.2 ⁇ 10 ⁇ 20 , and at pH 6, the solubility of copper is 14 mg-Cu / L, so that the copper separability is deteriorated.
  • the cementation method is a method in which a metal ion to be removed is reduced and removed by an electrically base metal. For this reason, if a base metal is used rather than copper, copper can be removed from a solution. For example, since cobalt is a base metal than copper, if cobalt metal is used, copper in the cobalt chloride solution can be precipitated and removed.
  • the base metal used is ionized and dissolved in the solution. Therefore, it is necessary to use a metal that can be dissolved, but the cobalt metal described above becomes a material for the positive electrode material. Even if it remains in the cobalt salt solution, the electrode performance is not affected.
  • cobalt metal is usually distributed as a cobalt plate, and it is difficult to obtain it in a reactive powder or briquette form. That is, when copper is separated from a cobalt salt solution using cobalt metal, there is a problem that the efficiency of removing copper is deteriorated because there is no choice but to use a cobalt plate having low reactivity. There is a need for a method of efficiently removing copper from a solution.

When the pH is higher than 2.5, the effect of removing the passive film is not sufficient, and the concentration of copper cannot be lowered sufficiently. On the other hand, when the pH is lower than 1.5, the nickel metal is dissolved regardless of the substitution reaction, so that the efficiency of depositing copper is deteriorated.
