2005-11-1 When calcium and carbonate ions have formed calcium carbonate and precipitated, the solution will be below saturation and more calcium hydroxide can dissolve. The commercially available carbonation process for PCC production is an example of this practice: the solid content of the slurry in the carbonation reactor is as high as 20% [17] .

2013-9-25 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 ...

2016-2-22 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 ammonium chloride, calcium chloride ...
