FLOWSHEET DEVELOPMENT STUDIES FOR GOLD AND CLAY CONTAINING SULPHIDE ORES

In this study, flowsheet development and economic approach studies have been carried outfor a sulphide ore containing gold and clay. For this purpose, previous beneficiation test resultswere used. First, clay separation was performed from the ore. In the following step, directleaching, gravity separation and flotation methods were tested and compared to obtain a goldpre-concentrates at different grinding sizes. According to the test results, 34% of the ore by masswas separated as clay concentrate, which was suitable for the ceramic industry. Different preconcentrateswere obtained from gravity and bulk sulphide flotation tests. The possible flowsheetalternatives were compared and discussed. Product specifications were discussed in terms ofeconomic and environmental aspects. As a result, producing Au containing flotation concentratewithout leaching was decided to be more economical. In this method, 34% of the ore could beobtained as a by-product. 77.77 g/t gold containing sulphide pre-concentrates can be obtainedwith a 70.05 % gold recovery.
