Nitric acid was found suitable and used for the extraction of copper and tin at room temperature. In the leached solution suspended tin and copper nitrates were obtained. Xray diffraction (XRD) and Energy dispersive Xray analysis (EDAX) was done to characterize the precipitate obtained. Copper in leached solution was recovered by cementation.
