- •
Sodium silicate is more effective than other depressants on iron oxides depression.
- •
Sodium silicate dosage, modulus and conditioning time affect iron ore flotation.
- •
Addition of hydrous calcium chloride enhances the silica separation from iron ore.
- •
An iron concentrate with Fe of 67%, SiO2 of 1.5% and P of 0.034%, is obtained.
