Abstract

La présente invention concerne un procédé d'extraction de métal précieux à partir de scories de convertisseur de nickel à faible matte. Le procédé consiste à : mélanger les scories de convertisseur de nickel à faible matte et de chaux vive, puis les calciner, obtenir un matériau calciné ; broyer et séparer magnétiquement le matériau calciné, obtenir du silicate et des scories riches en fer ; ajouter une solution alcaline forte aux scories riches en fer pour effectuer un traitement de lixiviation, et réaliser une séparation solide-liquide, obtenir un filtrat et un résidu ; mélanger le résidu avec une solution acide, réaliser une lixiviation acide à pression d'oxygène, et réaliser une séparation solide-liquide, obtenir un lixiviat et de l'oxyde de fer ; introduire du sulfure d'hydrogène gazeux dans le lixiviat, ajuster le ph, et effectuer une séparation solide-liquide, obtenir un précipité de sulfure de cuivre et un filtrat contenant du nickel-cobalt. Dans la présente invention, tout d'abord, l'élimination du dioxyde de silicium est éliminée par calcination pour préparer du silicate, puis de l'oxyde de fer est préparé au moyen d'une lixiviation acide, et enfin une séparation de métal est effectuée sur le lixiviat, ce qui permet d'utiliser efficacement divers composants des scories de convertisseur. Le flux de procédé de la présente invention est court et utilise efficacement chaque composant des scories du convertisseur de nickel à faible matte, les déchets sont transformés en matériau précieux, et la perte d'éléments métalliques précieux est réduite.
