Flotation Properties of FX-6 Collector in Scheelite-Sulfide Ore Concentration
The analysis of floatability of scheelite with FX-6 agent (produced in People's Republic of China) shows that, as against sodium oleate, FX-6 consumption is to be increased in the bulk flotation circuit by 25 % in order to have a comparable output. Given more stringent conditions in terms of depressor for retreating of rougher concentrates, the increased consumption of FX-6 enables obtaining the final concentrate with 60.4 % recovery of WO 3 where the increment by 0.63 % is thanks to essential reduction in sheelite loss in slurry. Based on the laboratory testing results, FX-6 agent is recommended for commercial trial.
