Crystallization from supersaturated cupric sulfate solutions in a batchwise stirred tank

Effect of Seawater on the Solubility and Physicochemical Properties of Acidic Copper Sulfate Solutions

“…Equilibrium studies have been performed for aqueous systems with inorganic salts in seawater, which have generated data for properties with similar salinities to seawater (Deng and Wang, Zhang and Han, Fabuss et al, Korosi and Fabuss, Fabuss et al) as well as the behaviors of copper in seawater and copper-chlorine using an Eh-pH diagram (González-Dávila et al, Glasby and Schulz, Beverskog and Puigdomenech, Bianchi and Longhi). Copper sulfate in distilled water solutions has been investigated for crystallization, supersaturation, equilibrium, and properties (Bester-Rogac, Taboada et al, Christov, De Juan et al, Giulietti et al, Giulietti et al, Ishii and Fujita, Linke and Seidell). Certain researchers have studied copper equilibrium in chloride solutions and estimated its properties (Lundström et al, Senanayake, Plyasunova et al, Wang et al, , Nila and González, Winand, Berger and Winand).…”

“…There are several methods for obtaining copper sulfate pentahydrate crystals (CuSO 4 Á5H 2 O), crystallization by cooling [3,4] or evaporating [5,6], both of which involve high energy requirements that raise operational costs. One of the methods to be explored is the addition of a third compound in the water-copper sulfate system, known as drowning-out crystallization [7], which decreases the solubility of the desired salt and causes copper sulfate crystallization.…”
