Detailed geological and drilling investigations have shown Kayabaşı deposit, located in Trabzon-Turkey, has a resource of 590 000 tons ore containing 2.2\% Cu and 1029 kg Au. The ore body shows the characteristics of both massive- and stockworktype sulfide mineralization. In this study, mineralogical analysis and flotation tests were performed to determine the degree of liberation of sulfides and the optimum grind time for the massive ore samples. Covellite and chalcocite were identified as the main copper mineral...

In this study, the recovery of barite and silver from G\"um\"uşk\"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\"uşk\"oy SilverPlant over the years. Multi Gravity Separator (MGS) produced a concentrate containing 65.00...
