“…Penelitian yang telah dilakukan mengenai produksi PCC telah banyak dilakukan dengan berbagai macam proses, dan penggunaan berbagai macam jenis pelarut yang bertujuan untuk meningkatkan kelarutan CaO dalam air. Altiner et al, 2021 meneliti pengaruh efek ultrasonik pada produksi partikel PCC dari desulfurasi gipsum dengan metoda direct mineral carbonation menggunakan konvensional dan venturi tube reaktor (menggunakan sumber alkali yang berbeda yaitu NaOH, KOH dan NH4OH).…”

ABSTRAK: Kualitas precipitated calcium carbonate (PCC) yang dapat digunakan di industri kertas dan cat harus bebas dari klorin, karena dapat menyebabkan korosi pada peralatan. Hasil penelitian skala pilot plant kapasitas 2 kg/jam, produk PCC masih mengandung klorin (0,73 s/d 2,02 %), sedangkan standar industri <0,001%. Penelitian ini bertujuan untuk menghilangkan kadar klorin dengan metoda pencucian dan filtrasi tanpa vakum dan metode kedua pencucian dan filtrasi dengan vacuum filter. Proses pencucian menggunakan air PDAM, air hujan dan aquadest dengan rasio PCC dengan air pencucinya yaitu 1:1, 1:2, 1:3 dan 1:4. PCC yang dihasilkan dari pilot plant dengan dua jenis PCC yaitu PCC dengan konsentrasi pelarut NH4Cl 12,5 g/L dan 50 g/L. Hasil penelitian menunjukkan penggunaan air PDAM dapat menurunkan kadar klorin 0,0322% (NH4Cl 12,5 g/L) dan 0,0959% (NH4Cl 50 g/L) dengan metoda pencucian dan filtrasi tanpa vakum dengan rasio 1:4. Kadar klorin yang diperoleh pada metode pencucian dan filtrasi dengan vacuum filter kadar klorin menjadi 0,0203% (pelarut NH4Cl 12,5 g/L) dan 0,0364% (pelarut NH4Cl 50 g/L). Morfologi PCC dipengaruhi konsentrasi NH4Cl. Kristal kalsit untuk konsentrasi NH4Cl (12,5 g/L) dan kristal aragonit untuk konsentrasi NH4Cl 50 g/L. Ukuran partikel yang diperoleh PCC 2 -5 µm. Kata Kunci: precipitated calcium carbonate; pencucian; filtrasi; klorin; kristal PCC

“…Additionally, HCl extracted calcium more efficiently than HNO 3 and H 2 SO 4 did. Thus, calcium carbonate from red gypsum mineralization is generally obtained via the swing process of adding H 2 SO 4 for leaching and then adding an alkali to adjust the pH [10,12,42].…”

“…Both reactors shortened the reaction time and produced nano-sized calcium carbonate. Altiner et al [10] used a Venturi reactor with an ultrasonic probe to improve the agglomeration of calcium carbonate. Konopacka-Łyskawa et al [94] used a bubble reactor to generate homogeneous vaterite calcium carbonate.…”

“…Although well developed, the conventional production methods have drawbacks such as high energy consumption and the depletion of natural ores [2,7,8]. To address these drawbacks, a novel method for producing calcium carbonate using calcium-containing industrial solid waste as a raw material rather than natural minerals has been developed [9,10]. Reacting CO 2 from flue gas with calcium from the industrial by-product gypsum (CaSO 4 ) produces calcium carbonate more economically than the traditional approach does by eliminating the additional stages of mining, grinding, and separation of natural minerals [11].…”

To avoid the long-term pollution of land and water by industrial gypsum by-products, the exploitation of this resource has become a priority. The indirect synthesis of calcium carbonate from the industrial by-product gypsum has received substantial attention as a viable method for resource utilization. Currently, the primary problems in the indirect manufacture of calcium carbonate from the industrial by-product gypsum are additive recycling and process simplification. This paper describes the present state of development and compares various indirect mineralization systems. The factors affecting leaching and mineralization in the indirect mineralization of CO2 from by-product gypsum and the management of CaCO3 crystallinity are discussed, and the current additive regeneration cycle is summarized. The applications of other technologies in the indirect mineralization of by-product gypsum are also summarized, as are the obstacles, and required future work. This review provides guidelines for the laboratory indirect mineralization of by-product gypsum as well as practical applications.
