  • Diatomite Minerals Education Coalition

    DescriptionRelation to MiningUsesThe term diatomite is applied both geologically and commercially to the nearly pure sedimentary accumulation of diatom frustules—the microscopic skeletons of unicellular aquatic algae belonging to the class of golden brown algae, Bacillariophyceae. The sediments are fine-grained, highly siliceous, and consist primarily of amorphous opaline silica with only minor amounts of organic residue, secondary minerals, and co-depositeSee more on mineralseducationcoalition.orgEstimated Reading Time: 4 mins
