For this purpose, previous beneficiation test results </p> <p>were used. First, clay separation was performed from the ore. In the following step, direct </p> <p>leaching, gravity separation and flotation methods were tested and compared to obtain a gold </p> <p>pre-concentrates at different grinding sizes. According to the test results, 34% of the ore by mass </p> <p>was separated as clay concentrate, which was suitable for the ceramic industry. Different preconcentrates </p> <p>were obtained from gravity and bulk sulphide flotation tests. The possible flowsheet </p> <p>alternatives were compared and discussed. Product specifications were discussed in terms of </p> <p>economic and environmental aspects. As a result, producing Au containing flotation concentrate </p> <p>without leaching was decided to be more economical. In this method, 34% of the ore could be </p> <p>obtained as a by-product. 77.77 g/t gold containing sulphide pre-concentrates can be obtained </p> <p>with a 70.05 % gold recovery. </p>}, number={3}, publisher={TMMOB Maden Mühendisleri Odası}
