sinter concentrate iron ore mining ball mill
The sinter grade concentrate was fed into the ball mill (ø100 × 1500 mm) at 500 kg/h. The pilot plant flotation operation was carried out sequentially in a bank of flotation cells of 0.13 m3 capacity each. The sinter grade iron ore was treated with 110 g/ton of Flotigam EDA as collector and 10 g/ton of flotanol M frother. The slurry pH
