Abstract

Crystallization patterns of high-copper matte with copper to nickel ratio (0.7-2.3):1, cooled in a regime close to the industrial one, have been studied. It is established that high-copper matte (Cu:Ni>1.6:1) is characterized by a different order of crystallization of structural components than traditional copper-nickel matte with a predominant share of nickel. The necessity of choosing a different cooling mode for cuprous matte is shown.
