  • Treatment of reclaim water for use in metals recovery
    Publication number: 20070039419
    Abstract: A process for improving the recovery of gold from gold-bearing solutions formed from carbonaceous ore using a cyanide lixiviant, the process comprising treatment of tailings pond water with H2SO5 before introduction into a gold-recovery system such that the water has a total concentration of CN? and SCN? reduced by at least 30%.

  • Nozzle for low pressure flash tanks for ore slurry
    Patent number: 6482250
    Abstract: A wear-resistant flash tank pressure let down nozzle for use in passing an ore slurry into an ore slurry flash tank to release steam from the slurry and reduce the pressure of the slurry. The nozzle has an expansion cone flaring toward the discharge end of the nozzle. The cross-sectional area of a choke section of the nozzle and the exit diameter of the expansion cone are selected to establish a relationship between pressure upstream of the nozzle and pressure in the flash tank so that underflashing, overflashing, and shock waves inside the flash tank are minimized.
    Type: Grant
