  • Zinc precipitation on gold recovery

    From leaching the pregnant solution is filtered off the solid particles that are suspended in it, expect for heap leaching where thickening is necessary. The clarified solution is de oxygenated in a vacuum tower. Zinc dust is then added to a solution of gold cyanide using a belt conveyer according . to the flow sheet above; vibrating tables could be used instead. This is where cementation

    The slurry settles naturally after hours of leaching. The clarified pregnant solution is discharged out of the leaching tank and flows into the pregnant solution pond, the barren solution is fed into the leaching tank to continue leaching and decantation. The gold extraction rate can be greatly improved by controlling the duration of leaching and decantation for repeating the cycle several times.
