  • Selective separation of cesium contaminated clays from

    01-01-2019· Based on those previous demonstrations, flotation is being considered in the current study to selectively separate Cs-loaded (contaminated) clays (Cs-MMT) from uncontaminated clays (MMT). Natural grade montmorillonite (MMT) was used throughout the study and was chosen due to its high cation exchange capacity (CEC) and high ion adsorption site density, both contributing to substantial
