  AP-42, CH 11.22: Diatomite Processing - U.S.

  2021625 · The crude diatomite is loaded on trucks and transported to the mill or to stockpiles. Figure 11.22-1 shows a typical process flow diagram for diatomite processing. The processing of uncalcined or natural-grade diatomite consists of crushing and drying. Crude diatomite commonly contains as much as 40 percent moisture, in many cases over …

  Natural diatomite process for removal of radioactivity from …

  200711 · The liquid waste contained three radionuclides (Cs-137, Cs-134 and Co-60). Following the treatment by diatomite, the radioactivity of liquid waste was reduced from the initial 2.60 Bq/ml to less than 0.40 Bq/ml. The results of this study show that most of the radioactivity was removed from the solution by processing with diatomite.
