Title (EN) PROCESS FOR THE PRODUCTION OF COPPER SULFIDE
(FR) PROCÉDÉ DE PRODUCTION DE SULFURE DE CUIVRE
Abstract:
(EN) A process for preparing a copper sulfide of the formula CuxSy, wherein the process comprises the following steps: (i) reacting an aqueous solution of a copper salt with a molar excess of a sulfiding agent so as to precipitate copper sulfide from the solution; (ii) isolating the copper sulfide precipitate from the reaction mixture; and (iii) drying the copper sulfide precipitate at a temperature of less than 100°C, wherein x and y are integer or non-integer values.
(FR) La présente invention concerne un procédé de préparation d'un sulfure de cuivre de formule CuxSy, le procédé comprenant les étapes consistant : à faire réagir une solution aqueuse d'un sel de cuivre avec un excès molaire d'un agent de sulfuration de façon à précipiter le sulfure de cuivre à partir de la solution ; (ii) à isoler le précipité de sulfure de cuivre du mélange réactionnel ; et (iii) à sécher le précipité de sulfure de cuivre à une température inférieure à 100 °C, x et y étant des valeurs entières ou non entières.
