Abstract

Se proporciona un método con el cual es posible, cuando se provoca que ocurra una reacción de sulfuración a partir de una solución ácida de ácido sulfúrico que contiene al menos níquel, a través del uso de un agente de sulfuración y la generación de un sulfuro de níquel, controlar adecuadamente el tamaño del grano del sulfuro generado mientras se mantiene una elevada eficiencia de reacción. El método de tratamiento de sulfuración de acuerdo con la presente invención comprende el suministro, a un reactor, de una solución ácida de ácido sulfúrico que contiene níquel, en donde se recupera el gas sin reaccionar entre el gas de ácido sulfhídrico agregado a la solución ácida de ácido sulfúrico, se agrega hidróxido de sodio al gas de ácido sulfhídrico recuperado, se genera sulfhidrato de sodio y la solución resultante de sulfhidrato de sodio se agrega a la solución ácida de ácido sulfúrico. En este momento, cuando se agrega la solución de sulfhidrato de sodio, el tamaño de grano del sulfuro de níquel generado se determina en 50 µm o mayor por tamaño de partícula al 50% (D50) mediante control de la cantidad de solución de sulfhidrato de sodio agregada al reactor al cual se suministra la solución ácida de ácido sulfúrico.</p>A method is provided with which it is possible, when a sulfuration reaction is caused from an acid solution of sulfuric acid containing at least nickel, through the use of a sulfurizing agent and the generation of a sulfide of nickel, properly control the size of the sulphide grain generated while maintaining a high reaction efficiency. The sulphuration treatment method according to the present invention comprises the supply, to a reactor, of an acid solution of sulfuric acid containing nickel, wherein the unreacted gas is recovered between the sulfuric acid gas added to the acid solution. of sulfuric acid, sodium hydroxide is added to the recovered hydrogen sulfide gas, sodium sulfhydrate is generated and the resulting solution of sodium sulfhydrate is added to the acidic sulfuric acid solution. At this time, when the sodium sulfhydrate solution is added, the grain size of the generated nickel sulphide is determined at 50 µm or greater by 50% particle size (D50) by controlling the amount of sulfhydrate solution of sodium added to the reactor to which the sulfuric acid acid solution is supplied. </p>
