The aim of this study was to investigate the production of precipitated calcium carbonate from marble wastes. Limestone is used as the source for the production of precipitated calcium carbonate. Marble wastes primarily constitute of CaCO 3. As the major content of the marble waste and limestone are the same, marble wastes can be used as an ...

In this work, experiments were performed to determine the filterability of calcium carbonate produced with an alternative calcium carbonate production concept. The concept uses steelmaking slag as raw material and has potential to fix CO2 emissions and utilize steelmaking slag, simultaneously. As calcium carbonate is precipitated in a solution containing …

The current precipitated calcium carbonate (PCC) production uses mined, crushed calcium carbonate as raw materials. If calcium silicates were used instead, carbon dioxide emissions from the calcination of carbonates would be eliminated. In Finland, there could, thus, be a potential for eliminating 200 kt of carbon dioxide emissions per year ...
