Umhlaba weDiatomaceous ufunyanwa ngokukodwa ngokugcoba, ukucola kunye nokuhlela ukufumana iimveliso ezimileyo, kwaye umxholo wayo ngokubanzi kufuneka ubuncinci ube ngama-75% okanye nangaphezulu kwaye umxholo wezinto eziphilayo ungaphantsi kwe-4%. Uninzi lomhlaba oline-diatomaceous ukukhanya ubunzima, ubunzima obuncinci, ukutyhoboza ngokulula, ukuhlupheka ngokudityaniswa, ukuphantsi kobunzima bomgubo owomileyo (0.08~0.25g / cm3), iyadada emanzini, ixabiso le-pH ngu-6~8, kufanelekile ukuba kusetyenzwe ngomgubo ophathwayo oPhetheyo. Umbala we-diatomite uhambelana nokucoceka kwawo.
