Published in 2018 at "Metallurgical and Materials Transactions B"

DOI: 10.1007/s11663-018-1247-2

Abstract: AbstractDuring smelting of copper sulfide concentrate, selenium is distributed between silica-saturated iron-silicate slag and copper-iron sulfide matte. The recovery coefficients of selenium between slag and matte were determined as a function of the initial concentration… read more here.
