Matte (métallurgie) — Wikipédia

20191117&ensp·&enspLa matte désigne une matière sulfurée semimétallique, produit intermédiaire dans les procédés pyrométallurgiques d'extraction de métaux non ferreux. Elle est le résultat de la première fusion d'un minerai sulfuré, par exemple de cuivre, de plomb, d'argent, d'antimoine ou de nickel.. La matte n'a d'intéret que par sa composition chimique et le fait qu'elle est en fusion [note 1].

Acid leaching of nickel sulphide concentrates ScienceDirect

In order to dissolve nickel from sulphide concentrates with dilute acids, a special "activation" pretreatment is required. In the present work, optimum activation was obtained by heating the concentrates at 750°C in an atmosphere of natural gas, the essential feature being to remove excess sulphur from the pyrrhotite present.
