Gold Extraction Recovery Processes

Feb 29, 2016  Riffles separate heavy and light particles. Gold recovery with sluices can vary depending on several factors. Fine gold losses can be minimized by cleaning up more frequently, reducing the speed of the slurry flow to around 0.50 to 0.80 m/s., and decreasing the feed size by performing a previous screening.
