Abstract
A process that produces pozzolanes, synthetic blast furnace slags, belite, or alite clinkers, as well as pig iron alloys, from oxidic liquid slag. The oxidic liquid slag is reduced above an iron bath in a reactor containing submerged tuyeres. Carbon is blown through the submerged tuyeres and into the iron bath to maintain the iron bath at a carbon content of between 2.5 wt % and 4.6 wt %.
