Lime-concentrate roasting studies––effect of activated

2004-3-1 · The principal conclusion that can be drawn from the work described here is that, by an appropriate selection of roasting conditions, pellets of copper concentrate and activated limestone can be roasted in air to give a completely roasted product in about 40–50 min with very low emission of SO 2 which is appropriate for recovering copper by further leaching.

[PDF] Lime-concentrate roasting studies––effect of

Abstract The roasting in air of pellets consisting of copper–iron sulphides and limestone and activated limestone has been investigated to explore the possibility of developing a metal production process that eliminates sulphur dioxide gas emissions. The effects of pellet porosity, sulphide: limestone ratio, pellet sizes and temperature on reaction kinetics were investigated.
