Özet
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.
