ABSTRACT:
Unique pink/salmon diatomite agglomerates, well suited as filtering agents/aids, have a cristobalite content of less than 1.5%, a permeability ranging from 20 to 500 millidarcys, a cake density of less than 0.400 g/cm.sup.3, and are prepared by homogeneously intimately admixing a diatomite with a binder solution of silicic acid or of an alkali metal silicate, drying and optionally gently grinding the agglomerates thus formed, and then calcining the agglomerates at a temperature no greater than 850.degree. C., preferably no greater than 600.degree. C.
