Abstract

The research results on gravity concentration of the Shalkiya deposit lead-zinc ore are presented. Using the float-and-sink analysis data, the Henry-Reinhard-type washability curves are calculated and plotted for separation size grade 40–8 mm. The separation density required for recovery of light fraction at minimum possible loss of lead and zinc, as well as the gravity washability indices are determined. It is found that the overhead product of the gravity concentration of coarse ore is tailings containing silicon, calcite and carbon black dioxides. The loss of lead and zinc is minor. Processing of coarse crushed ore should be carried out in heavy medium.
