This paper presents the results of a study performed on silica sand samples to determine the effect of operating parameters (collector type and dosage, solids content in the pulp, pulp pH and air flow rate) on the concentrate grade and mass recovery in laboratory-scale column flotation. Through the analysis of variance (ANOVA), it was …
Flotation is a widely used method in mineral processing to separate valuable minerals from unwanted gangue. It relies on the differences in surface properties of various minerals.
The secondary electrostatic separation focuses on separating the remaining minerals (e.g. zircon sand, silica and rutile). When processing beach sands and similar minerals reserves, the electrostatic separator has the advantage of processing materials in a dry state (unlike froth flotation).
