In this study, flowsheet development and economic approach studies have been carried out
for a sulphide ore containing gold and clay. For this purpose, previous beneficiation test results
were used. First, clay separation was performed from the ore. In the following step, direct
leaching, gravity separation and flotation methods were tested and compared to obtain a gold
pre-concentrates at different grinding sizes. According to the test results, 34% of the ore by mass
was separated as clay concentrate, which was suitable for the ceramic industry. Different preconcentrates
were obtained from gravity and bulk sulphide flotation tests. The possible flowsheet
alternatives were compared and discussed. Product specifications were discussed in terms of
economic and environmental aspects. As a result, producing Au containing flotation concentrate
without leaching was decided to be more economical. In this method, 34% of the ore could be
obtained as a by-product. 77.77 g/t gold containing sulphide pre-concentrates can be obtained
with a 70.05 % gold recovery.
