Roasting an overview | ScienceDirect Topics

The first stage is a partial roasting operation where partial oxidation of the sulfur provides process heat for arsenic compound volatilization (dealt with in the gas cleaning section) while oxygen is absent from the process gas Such unit operation is also found in dearsenifying copper roasting The second stage is carried out in oxygen excess and aims at the complete oxidation of sulfide
