Abstract
The low grade mineral needs pre-treatment operation prior to concluding processing. This is especially proper for uranium and gold mineral naturally forming low grade into crest of the earth. This paper surveyes the enhancement of uranium ore grade in Saghand by using gravity separations methods. The mineral deposits grade is low and refractory within this realm. The study of mineralization demonstrated that uranium ore type is Davidite and the average content of the uranium specified by X-ray diffraction analysis was 300ppm. Also, the amount of other minerals were 57.39% (SiO2), 1.29% (TiO2), 5.64% (Fe2O3) and the contented value of rare earth elements, as well. The initial step of processing operation is to release the elements, particularly uranium. Therefore, the ore sample is crushed by jaw and roll crusher and then ground by rod milling to gain access to suitable degree of liberation. The milling output size was classified by the laboratory screens and divided into six sections. Each section of the screened product was washed by water and separated by shaking table. The results confirmed an increase in the grade of uranium and other minerals up to 4463ppm.
