Usage of zeolite raw materials as natural barrier for conservation of nuclear waste

Abstract: The presence of manganese oxides and hydroxides forming thin crusts up to 4-5 mm thick, deposits and impregnations with black color was found in the pink-reddish clinoptilolite zeolites from the field works in the area of the Most deposit, Bulgaria. The aim of the present research is to study the zeolite raw material in the area of the deposit in order to determine the manganese mineralization. The presence of certain microporous minerals, referred to as octahedral molecular sieves (OMS) and octahedral layered materials (OL) will increase the value of the zeolite raw material from the deposit in order to use them as a sorbent of heavy metals and radionuclides to solve some ecological problems.
