This research focused on the preparation of new zeolite by hydrothermal method after analysis and purifying the clay ores and using their components (silicates and aluminates) into the preparation of zeolite that were separated from these ores by chemical methods. The clay ores were pre- diagnosed through chemical analysis, X-ray fluorescence and diffraction(XRF & XRD). The zeolite was prepared using the structure-directing agent (Triethylene glycol anhydrous), then the zeolite was loaded with transition metals of (Ag, Cu, Co, Ni and Cr) as well as (Na, K and Ca). Then, the zeolite samples were studied using (XRD), (XRF), BET method, and scanning electron microscope (SEM). It was found that the prepared zeolite have a good porous and crystal structure, beside the good surface area, which was (70.239 m2/gm) and reached to (106.759 m2/gm) in the Cr-loaded zeolite. The antimicrobial activity of the prepared zeolite samples was studied and it was found that the zeolite samples loaded with (Ag, Cu and Ni) are the best in terms of antibacterial activity towards Staphylococcus and Candida albicans.
