Abstract Scope In order to produce a high-grade copper sulfide (Cu2S) directly from Cu ore, a new selective chlorination process using metal chloride as a chlorinating agent was developed. Various types of Cu ores were reacted with the chlorinating agent in the presence of sulfur (S) or without S in a quartz crucible under Ar gas atmosphere at 900 – 1100 K for 5 h. Experimental results show that iron (Fe) in the ore was selectively removed as ferrous chloride (FeCl2), and high-grade Cu2S was obtained in a single step. Mass percent of Fe decreased from 23.6 % in feed to 0.12 % in residue, and Fe removal ratio reached 99.5 % under certain conditions. Therefore, this new selective chlorination of Cu ore using metal chloride is feasible to produce high-grade Cu2S.
