     due to low contents of radioactive materials in the zarigan ore, the beneficiation process is necessary. x- ray diffraction analysis revealed that the ore contains numerous amounts of minerals such as sio2, fe2o3, tio2 and rare earths. in this study, the upgrading of thorium and uranium in zarigan deposit has been investigated by gravity, magnetic and electrostatic separations methods. the output of jaw crusher was ground to 100% - 85 micron using ball mill. then about 95% of sio2 was removed by shaking table. processing of heavy concentrate of shaking table using high intensity magnetic separator eliminated other impurities and the rest of liberated silica. the obtained magnetic concentrate was treated by low intensity magnetic separator and its efficiency for thorium separation was high. finally, the non magnetic concentrate was processed with electrostatic separation. the contents of thorium and uranium in the final non magnetic concentrate increased to 4000 and 5000 ppm respectively and only 15 % of initial feed (ore) was transferred to this concentrate. therefore, this will result to decrease of acid consumption and increase the efficiency of next leaching process. the beneficiation circuit of the ore was proposed as jaw crusher-ball millshaking table-high magnetic separator-low magnetic separator.
