A method for increasing the chrome to iron ratio of a chromite product selected from the group consisting of ore and ore concentrate comprising the steps of mixing the chromite product with at least one salt so as to produce a mixture, whereby the concentration of salt in the mixture is selected to induce the selective chlorination of iron; and chlorinating the mixture in the presence of CO at a temperature sufficient to induce the formation of a thin film of a melt around the chromite product and at a temperature able to promote the selective chlorination of iron, whereby an iron impoverished chromite product is yielded having an increased chromite to iron ratio as compared to that of the chromite product.
L'invention concerne un procédé permettant d'accroître le rapport chrome-fer d'un produit chromite choisi dans le groupe formé de minerai et de concentré de minerai, qui consiste à mélanger le produit chromite à au moins un sel de façon à produire un mélange, la teneur en sel du mélange étant choisie de manière à induire la chloration sélective du fer, et à chlorer le mélange en présence de CO à une température suffisante pour induire la formation d'un film mince d'une matière fondue autour du produit chromite et à une température susceptible de favoriser la chloration sélective du fer, ce qui permet d'obtenir un produit chromite appauvri dont le rapport chromite-fer est accru comparé à celui du produit chromite.
