Recovering molybdenite from ultrafine waste tailings by

Dec 01, 2012· As seen from Table 4, in normal production processes of agglomeration flotation, 95% molybdenum is recovered into the froth products (concentrate) with a molybdenum grade at 22.62%, and only 5% molybdenum still lost in secondary tailings. The molybdenum grade in the final tailings is 0.056%, which is far lower than the feed that is 1.05%.

Gold Tailings Reprocessing Technology

In general, the gold recovery method of gold tailings is mainly the all-slime cyanidation CIP method. It is the recovery of residual gold particles from tailings by using the property of gold soluble in cyanide. The gold recovery for large capacity and low-grade gold tailings is common heap leaching.
