Copper dross(CD) is a waste product formed during copper doping where sulphur was added to the tin metal during refining process to remove copper in the form of copper sulphide. CD was found to contain significant amount of tin and other valuable metal such as copper that could be trapped during copper doping process. The main objective of this work is to assess the potential of CD as a secondary resource for tin product and the applicability of hydrometallurgical process to extract tin and copper. Two main parts involves in this work are CD characterization and recovery of tin by acid leaching. From elemental composition analysis by XRF, in CD sample, amount of SnO2 present is about 63% followed by SO3 with 14%, Fe2O3 is 9% and CuO with 2.5%. Cassiterite and magnetite is the main phases found by XRD analysis. From the leaching study, it was found that almost 60% of tin has been dissolved in acid solution at condition of 80 °C, 2 M HCl with 8 hours leaching time.
