ammonia. The water balance is controlled by evapora-tion after the ammonia regeneration. Calcium chloride is regenerated into hydrochloric acid and the solution is returned to leaching. In total, the leaching process takes about 10 to 15 hours to complete. The leaching residue weight is about 25 percent of that of the matte fed into the process.

ABSTRACT researchrepository.murdoch.edu.au

Nickel matte is a nickel &de concentrate produced by smelting. It consists mainly of two components: a nickel-copper alloy and heazlewoodite (Ni3S2); but also contains varying amounts of djurleite, CU~.~~S. There are several hydrometallurgical routes for processing nickel matte. The most recent of these involves an oxidative leach in acid chloride or sulfate solution. Nickel is subsequently
