In this study, the amenability of Akoluk (Ordu -Turkey) ore to the extraction of gold and silver by cyanide leaching was investigated. Mineralogical analysis of the ore has revealed the presence of native gold and a variety of minerals including barite, zinkenite, stibnite, orpiment, realgar, cinnober, pyrite and sphalerite. No silver was detectable under microscope suggesting that it could be present as occluded in minerals such as fahlerz, antimonite and zinkenite. Gold particles as 1-88 $\mu$m in size were obse...

In this study, the geological features of the placers in the Aegean region of Turkey and possible processing options for the recovery of precious metals and industrial raw materials were examined. Industrial raw materials present in the placers and their potential for industrial uses were reviewed. A conceptual flow sheet for the production of a bulk concentrates to recover rutile, ilmenite, zircon, hematite, limonite, magnetite, cassiterite and gold contained in the placers concentrate was proposed. Quartz crysta...
