I-Carbonatites ngamatye e-plutonic avuthayo kunye nomxholo we-carbonate ongaphezulu kwe-50 wt.% (ngokuqhelekileyo i-calcite, i-dolomite, okanye inqabile i-natrite carbonate). I-carbonate mineralogy yabo ephezulu ibenza bangabi yodwa ngokwejoloji kuphela, kodwa kunye nezixhobo ezixabisekileyo ze-phosphate kunye nokutsalwa komhlaba onqabileyo. Ukuze ezi zimbiwa ziqhubeke nokucutshungulwa kwilabhoratri, iplanti yokulinga, okanye kwinqanaba lemizi-mveliso, iliwa kufuneka lincitshiswe kuqala libe kubungakanani obuziinkozo obuchaziweyo ngenkqubo yokubuyisela.
IiCarbonatites
I-Carbonatites ene>50% ye-carbonate (i-calcite, i-dolomite) zizinto eziphathekayo ezixabisekileyo. Funda indlela yokuphucula ukuhanjiswa ukusuka kwilabhoratri ukuya kwi-phosphate yeshishini kunye nokutsalwa kwe-REE.
