Acicular Calcite And Aragonite Calcium Carbonate
Jul 18, 2020 The selective extraction of calcium from the slag prior to carbonation allows the formation of a pure and marketable precipitated calcium carbonate (PCC) with different crystalline polymorphs, i.e. aragonite, vaterite, calcite, and or with different crystal habits, i.e. rhombohedral, hexagonal prism, scalenohedral, cubic and prismatic.Jul 10, 2017 Recently, a precipitated calcium carbonate (PCC) production technology utilizing steel converter (basic oxygen furnace) slag as a calcium source, referred to as Slag2PCC, has been developed and demonstrated successfully by researchers at Aalto university together with their collaborators (Said et al., 2013, 2016 Mattila et al., 2014).
