Studies on selective flocculation of low-grade iron ore using .

The response of low-grade iron ore flocculation was investigated using a two-level and three-variable factorial design. From the studies, the optimal conditions were found to be pH (10), pulp density (6%), and flocculant dosage (0.5 mg/g), and the estimated values of for grade and recovery were 67.52% and 80.17%,.

Studies on selective flocculation of low-grade iron ore using .

behavior of different variables of selective flocculation such as pulp density, pH and flocculant dosage were varied. The response of low grade iron ore flocculation to this variation was investigated using 23 factorial designs. From the studies, optimal condition established were found to be pH (10), pulp density (6%) and.

Optimization of mill performance by using online ball and pulp .

(Figure 6.) The pulp density is an important parameter which influences the grinding efficiency. In iron ore, for instance, a variation of 2 to 3% solid content in the slurry could lead to a difference up to 10% on the energy (kWh/T) for a similar grind. Optimization of mill performance by using online ball and pulp measurements.
