Abstract
The tailings produced from the calcination of Bigadic colemanite ore a re upgraded by means of a gravity concentration method. The experiment s were conducted in two separate fractions. The coarse (- 1 + 0.5 mm) and the fine (-0.5 mm) tailing fractions containing respectively 20.01 % and 36.31% B2O3 were treated on a Deister Superduty Diagonal Deck la boratory concentrating table. Under the optimum conditions, a colemani te concentrate assaying 51.01% B2O3 with 68.67% recovery was obtained. The combined results of calcination and tabling resulted in a final c oncentrate containing 51.88% B2O3 with an 84.41% recovery rate.
