recovery silver from silver cyanide mud
TEST WORK INDICATES OVER 90% SILVER RECOVERY TO .
applications SVL would expect to recover over 95% of the silver from the silver cyanide solution, thus delivering greater than 90% silver recovery overall to doré bars . The Company will continue optimisation testwork and is aiming to demonstrate silver recoveries to doré of over 90% are commercially achievable.
