The most important Iranian boron reserves are in the basin of GHEZEL-OUZAN, a river in the West and Northwest area of Zanjan. The majority of these mines have been extracted with a non-advanced way. There are many great waste damps next to the mines which are a threat to the environment for releasing boric acid and because of an average grade of Boron are valuable from financial point as well. Present paper studies possibility of concentration a low-grade boron waste from Moshampa boron mine using shaking table. In order to concentration, 6 factors in 5 levels were considered. The factors included: particle size, water flow rate, frequency, liberation range, tilt angle and feed rate. Optimization was carried out by classic method (one factor at the time). As a result, optimum condition obtained under particle size of +1.18 -2 mm, water flow rate of 3.5 lit/min, frequency of 320 cycle/min, liberation range of 15 mm, tilt angle of 8 degrees and feed rate of 250 g/min. This test yielded 58.43% of B2O3 recovery under optimum conditions performance, and a concentrate with 26.45% B2O3 was produced.
