Abstract

Magnetite and hematite concentrates are produced in Chadormaloo mineral processing plant in three parallel lines. Apatite as gangue of iron ore is now removed by mechanical flotation method using sala cells. In order to reduce more apatite from hematite concentrate, the replacement of mechanical floatation with column floatation cell was investigated. For this purpose, a lab column cell was used with diameter and height of 74 and 1535 mm, respectively. In this research, for the optimization of type and dosage of reagents (depressant and collector-frother) in hematite flotation at rougher stage, several reagents were applied including Asame, Atrac 1580, Flo_G30, Asame+Atrac, as collector-frother and also sodium silicate, dextreen+starch, as depressant. Therefore, Asame+Atrac and sodium silicate were selected as suitable collector-frother and depressant, respectively. In the next stage, reagent dosage was also optimized as follows: Asame+Atrac: 150 g/t, ratio of Asame/Atrac: 70/30, sodium silicate: 800 g/t. Under these conditions, separation efficiency was obtained 56%.
