ABSTRACT

In this study, the recovery of barite and silver from Gümüşköy Silver Plant
(Turkey) tailings was investigated using Multi Gravity Separation and cyanidation
methods. Approximately 20 million tons of tailings contain 20.62% BaSO4, 51.15%
SiO2, 11.5% CaCO3, 3.84% Fe2O3, 4.76% Al2O3 and 120 g/ton silver with a particle
size of 70% passing 37 μm have been disposed of to the tailings pond in Gümüşköy
SilverPlant over the years.
Multi Gravity Separator (MGS) produced a concentrate containing 65.00 %
BaSO4 at 35.62% recovery from tailing sample as-received 81.42% BaSO4 at 22.85%
recovery from -37 μm tailings. These concentrates were suitable in quality for use in
the drilling and chemical industry. Silver recovery was found to be 37% from the -37
mm fraction. By the proposed flowsheet in this research, approximately 432 tons of
Ag could be produced with an economic potential of 80 million dollars.
