الحصول على السعرThe enriched ore is roasted with just enough air to convert the iron sulfide to iron(ll) oxide: The solid mixture is then mixed with calcium carbonate (limestone), silica (sand) and heated to 1300 K. The iron forms a silicate slag and the copper(I) sulfide melts and sinks to the bottom of the furnace.
