CHARACTERIZATION OF PRODUCTS AND ANALYSIS OF SULFUR VAPORIZATION FROM AN IRON SULFIDE ORE

The total extraction of sulfur by vaporization from iron sulfide ores leads to a residue that is constituted in great part of iron. The aim of this article is to follow up the secondary metals composition in the residue during the sulfur extraction. When the pyrrhotite is treated alone, copper is co...

Description
Summary:The total extraction of sulfur by vaporization from iron sulfide ores leads to a residue that is constituted in great part of iron. The aim of this article is to follow up the secondary metals composition in the residue during the sulfur extraction. When the pyrrhotite is treated alone, copper is completely evaporated after Cu 2 S decomposition. While in the presence of carbon, iron is present as the core form in the iron sulfide. In this case, the kinetic of vaporization is fast and no secondary metals trace is detected in the iron core.
