Definitions

  • the sulfide production method of the fifth invention is characterized in that, in the fourth invention, the aqueous solution containing sodium hydrosulfide is temporarily stored and then supplied to the reaction starting solution.
  • the reaction starting solution is nickel obtained by removing impurities from a leachate obtained by leaching a slurry containing nickel oxide ore with sulfuric acid. It is a mother liquid for collection.
  • FIG. 3 is an explanatory diagram of a sulfide production facility in Comparative Example 1.
  • FIG. It is a graph which shows the relationship between a sodium hydrosulfide addition ratio and nickel poor solution pH. It is a graph which shows the relationship between a sodium hydrosulfide addition ratio and nickel recovery. It is a graph which shows the relationship between a sodium hydrosulfide addition ratio and hydrogen sulfide reaction efficiency. It is a graph which shows the relationship between a sodium hydrosulfide addition ratio and sodium hydroxide basic unit. It is explanatory drawing of the conventional manufacturing equipment.
  • the pH of the reaction starting solution 11 is not particularly limited, but is preferably 3.0 to 3.8 in order to promote the sulfurization reaction of nickel and cobalt. This is because if the pH of the reaction starting solution 11 is less than 3.0, iron, aluminum, and the like cannot be sufficiently removed in the previous neutralization step. On the other hand, if the pH of the reaction starting solution 11 exceeds 3.8, nickel or cobalt hydroxide may be generated.
  • Hydrogen sulfide is dissolved in the reaction end solution 14 stored in the reaction end solution storage tank 2. This hydrogen sulfide is discharged from the sulfurization reaction vessel 1 and part of the hydrogen sulfide is discharged as the temperature and pressure drop. For this reason, the exhaust gas 21 discharged from the reaction final liquid storage tank 2 contains hydrogen sulfide gas. Note that the amount of hydrogen sulfide gas discharged from the reaction final solution storage tank 2 is smaller than the amount of hydrogen sulfide gas discharged from the sulfurization reaction vessel 1. Therefore, the hydrogen sulfide concentration of the exhaust gas 21 discharged from the reaction final solution storage tank 2 is lower than the hydrogen sulfide concentration of the exhaust gas 17 discharged from the sulfurization reaction vessel 1.
  • the sodium hydrosulfide storage tank 5, the pipe 6, and the pump 7 correspond to the “circulator” described in the claims.
  • the circulation device is not particularly limited as long as the absorbing solution 23 discharged from the second gas cleaning tower 4 can be supplied to the sulfurization reaction vessel 1 as an aqueous solution 13 containing sodium hydrosulfide. Moreover, it is good also as a structure which is not equipped with the sodium hydrosulfide storage tank 5. FIG.
  • the amount of the aqueous solution 13 containing sodium hydrosulfide generated by the first gas cleaning tower 3 and the second gas cleaning tower 4 is determined to be a sulfurization reaction vessel.
  • the amount is larger than the amount supplied to 1 (reaction starting solution 11)
  • the surplus can be stored.
  • the amount of the aqueous solution 13 containing sodium hydrosulfide generated by the first gas cleaning tower 3 and the second gas cleaning tower 4 is smaller than the supply amount to the sulfurization reaction vessel 1 (reaction starting liquid 11), temporary storage is performed.
  • U is the sodium hydroxide basic unit
  • W NaOH is the amount of sodium hydroxide used in the first gas cleaning tower 3 and the second gas cleaning tower 4
  • W Ni is the amount of nickel obtained as a sulfide.

Abstract

L'invention concerne : une installation de fabrication de sulfure qui permet d'obtenir une utilisation efficace de sulfure d'hydrogène gazeux et donc d'améliorer le rendement de la réaction de sulfure d'hydrogène ; un procédé de fabrication de sulfure. Cette installation de fabrication de sulfure est pourvue : d'une cuve de sulfuration (1) dans laquelle un liquide de départ de réaction (11), du sulfure d'hydrogène gazeux (12) et une solution aqueuse contenant du sulfure d'hydrogène (13) sont fournis ; d'une cuve de réserve de liquide de fin de réaction (2) à laquelle un liquide de fin de réaction est fourni ; d'une première tour de lavage de gaz (3) dans laquelle du sulfure d'hydrogène gazeux (17) sortant de la cuve de sulfuration (1) est absorbé par une solution aqueuse d'hydroxyde de sodium (19) ; d'une seconde tour de lavage de gaz (4) dans laquelle du sulfure d'hydrogène gazeux (21) sortant de la cuve de réserve de liquide de fin de réaction (2) est dissous par une solution aqueuse d'hydroxyde de sodium sortant de la première tour de lavage de gaz ; d'un système de circulation (6) pour fournir une solution aqueuse contenant du sulfure d'hydrogène (13) sortant de la seconde tour de lavage de gaz (4) à la cuve de sulfuration (1). Ainsi, le sulfure d'hydrogène gazeux (17, 21) peut être efficacement utilisé, ce qui permet d'améliorer le rendement de la réaction de sulfure d'hydrogène.
