  • 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
    Filed: February 28, 2000
    Date of Patent: November 19, 2002
    Assignee: Barrick Gold Corporation
