Fig. 8c displays the manufacturing process to produce Cu(NO3)2.3H2O. The process starts from the mining and extraction of metallic copper (Cu). After mining, Cu is mixed with nitric acid (HNO3) according to the Ullman's encyclopedia [12]. The reaction between Cu and HNO3 is shown in Eq. (7). The effluent from the reaction step is evaporated and concentrated to obtain crystals of Cu(NO3)2.3H2O. To determine the amount of crystal, solubility of the hydrated copper salt was considered as 77.4 g Cu(NO3)2.3H2O per 100 g water.
