This paper presents the results of magnetic separation tests for the recovery of colemanite from the ore and the tailings produced in Kestelek (Turkey) Processing Plant. Crushed ore (30.76\% B2O3) and tailings (31.76\% B2O3) samples were wet screened and classified into different size fractions. Size fractions coarser than 75 $\mu$m were subjected to three-stage magnetic separation using a high intensity permanent magnetic separator. The mineralogical composition of the ore and the tailings appears to enable gangu...

In this study, the recovery of barite and silver from G\"um\"uЕџk\"oy 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 $\mu$m have been disposed of to the tailings pond in G\"um\"uЕџk\"oy SilverPlant over the years. Multi Gravity Separator (MGS) produced a concentrate containing 65....
