Abstract

Thorium extraction and possible separation from monazite leaching solution was studied. Primary amine Primene JM-T was selected for thorium extraction processing. Various experiments were tested and established for the thorium liquid -liquid extraction process. The screening of extractant, lower pH conditions, extractant variation and extraction isotherms construction, and finally, stripping studies were established.
