Table 1 shows the chemical composition of each diatomite. It is observed that all samples are mainly composed by SiO 2, between 47 and 74%, which indicates a low concentration of SiO 2 for a diatomite that is going to be used in the removal of heavy metals, since they normally contain values greater than 60% and up to 90% (Fowler et …

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 60 percent. …

INTRODUCTION. Diatomite rock is a loose, earthy or loosely cemented porous and lightweight rock of sedimentary origin, mainly formed by fragments of armor (skeletons) of diatom algae: diatomea and radiolaria. Diatomite is a microscopic diatom alga whose size ranges from 0.75 to 1500 m; sometimes this rock is called infusorial earth, …
