Diatomite Filter Aid (Mining Grade)
CAS Number: 61790-53-2
Diatomite (diatomaceous earth) filter aids are used in mineral processing and hydrometallurgy to improve filtration rates and produce clearer filtrates from fine mineral slurries and process solutions. Pre-coat filtration with diatomite allows filtration of ultrafine particles and colloidal materials that would otherwise blind standard filter media. Mining-grade diatomite is widely used in gold CIL/CIP solution polishing, cyanide leach solution clarification, and concentrate filtration.
