1. Ukwakheka kweCalcium Carbonate: Ummangaliso weJiyoloji owadalwa yiNdalo kunye neKhemistri

Eyona nto iphambili kwi-calcium carbonate yendalo yenziwa ngeenkqubo zejoloji nezebhayoloji kwiminyaka ezizigidi. I-calcium carbonate enzima (iGround Calcium Carbonate, GCC) ivela kumatye amdaka anjengelimestone, i-calcite, kunye nemarble, eyenziwe kukuqokelelwa kwamaqokobhe ezinto eziphilayo zaselwandle kunye namathambo kwiilwandle zamandulo. Ngeenkqubo ze-tectonic, ezi deposits zadityaniswa zaza zaqiniswa zaba ziiminerali ezicocekileyo kakhulu. I-calcium carbonate ekhaphukhaphu (iPrecipitated Calcium Carbonate, PCC) yenziwa ngeenkqubo zeekhemikhali—ilimestone ifakwa i-calcium oxide ukuvelisa i-calcium oxide, ethi emva koko ifakwe i-hydrated kwaye ifakwe i-carbonate kunye ne-CO₂ ukwenza amasuntswana aqhekekileyo kakhulu. Ngexesha lezi nkqubo, i-calcium carbonate iphuhlisa iimpawu zayo eziphawulekayo—ubumhlophe obuphezulu, ubungakanani bamasuntswana alawulwayo, kunye nokusebenza okuguquguqukayo, ngaloo ndlela ibeka isiseko sezicelo zayo ezibanzi zoshishino.

Namhlanje, iidipozithi zekhabhoni ze-calcium ezikumgangatho ophezulu kunye neendawo zokuvelisa zisasazwa kwihlabathi liphela. Iindawo eziphambili zokuvelisa ziquka iTshayina, i-United States, iYurophu, kunye neJapan.
