2.2. Development of the In-Pulp optical measurement apparatus. The flotation pulp samples were fit into a 10 mm × 10 mm × 45 mm cuvette. The total mass for each sample was about 3 g with the samples split to −38 µm (fines) and + 38 µm (coarse) as the fines and slimes obscured the optical microscopy images when combined.

Abstract. Pulp chemical conditions: pH, E h, O 2 levels, conductivity, concentration of cations and anions, particle size and shape were measured in conventional and autogenous circuits of a plant treating a low grade copper ore. Results of particle size and shape analyses and pulp chemical conditions show some differences for the ores …

The pulp rheology is an important factor affecting flotation performance. Gangue minerals have a significant impact on the rheological property of smithsonite (ZnCO3). The complex pulp rheology (high viscosity, poor dispersion) will adversely affect the grade and recovery of concentrate. To address this problem, the effect of gangue …
