Critical copper concentration in sphalerite flotation

2016-1-10  The copper concentration of 1 × 10 − 5 M corresponds very closely to the maximum in sphalerite flotation (Fig. 2) and the solubility limit of copper hydroxide of 6.8 × 10 − 6 M (Section 3.1), which indicates that copper hydroxide precipitation on the sphalerite surface is responsible for the decrease in sphalerite hydrophobicity.

Critical copper concentration in sphalerite flotation

Sphalerite flotation is dependent on copper concentration and temperature. • It increases at low copper concentration because of copper activation. • It decreases at high copper concentration because of copper hydroxide precipitation. • Sphalerite flotation is reduced when temperature is below 12 °C.
