Abstract

Gold concentration processes usually consist of gravity separation, flotation, cyanidation or a combination of these processes. Actually, the choice of those processes depends on the mineralogical characterization and gold content of the ore. Recently, the recovery of gold using gravity methods has gained importance because of its cost and harmless. In this study, pre-concentrates of gold were produced in the different type of ores by multi stepwise gravity separation techniques. The Knelson concentrator and shaking table was used for recovery of gold. The first gold bearing ore containing around 0.6 g/t Au was taken from Manisa Region, western part of Turkey. At the end of the stepwise Knelson following shaking table experiments, a gold pre-concentrate containing 170 g/t Au was obtained with 80% recovery. Another gold bearing ore sample containing 5.83 g/t Au was taken from Gümüşhane Region, northern east part of Turkey. At the end of the stepwise Knelson concentration experiments, a concentrate containing around 620 g/t Au was recovered with 41.4% recovery.
