Gold concentration usually consists of gravity separation,flotation,cyanidation,or the combination of these processes.The choice among these processes depends on the mineralogical characterization and gold content of the ore.Recently,the recovery of gold using gravity methods has gained attention because of low cost and environmentally friendly operations.In this study,gold pre-concentrates were produced by the stepwise gravity separation and flotation techniques.The Knelson concentrator and conventional flotation were employed for the recovery of gold.Gold bearing ore samples were taken from Gümtü(s)hane Region,northern east part of Turkey.As a result of stepwise Knelson concentration experiments,a gold concentrate assaying around 620 g/t is produced with 41.4wt% recovery.On the other hand,a gold concentrate about 82 g/t is obtained with 89.9wt% recovery from a gold ore assaying 6 g/t Au by direct flotation.
