Thiocyanate hydrometallurgy for the recovery of gold.: Part II: The leaching kinetics

Acid thiocyanate leaching of gold was investigated in the presence of ferric sulfate as an oxidant. According to leaching kinetic studies the initial rate of gold leaching is slow, and not significantly dependent on thiocyanate (0.05-0.2 M) and ferric (0.1-1.0 g/L) concentrations. Ferrous and cupric ions had no effect on leaching kinetics under the conditions studied. In contrast, silver (I) and copper (I) ions significantly impeded the rate of gold leaching. The electrochemical experiments (linear sweep voltammetry and chronoamperometry) indicated that the anodic reaction for gold leaching in acid thiocyanate solutions is the limiting step for the leaching process. Gold dissolution and thiocyanate oxidation participate simultaneously in the anodic process. The addition of thiourea noticeably enhanced the rate of gold leaching. Fourier transform infrared spectroscopy (FTIR) studies demonstrated that thiocyanate and its complexes with the metal ions involved in the leaching systems (Fe (III), Cu (II), Cu (I) and Ag (I)) had very weak adsorption properties at the gold surface.

Structural studies on tris(2-cyanoethyl)phosphine complexes of Cu(I): The sensitivity of the secondary nitrile coordination to the nature of the anion

Tris(2-cyanoethyl)phosphine (tcep) reacts with the copper(I) compounds, CuX (X = Cl, Br, I and SCN), in a 1:1 ratio to give 1:1 complexes, CuX(tcep), whereas it reacts with CuY (Y = PF6, ClO4, NO3, BH4, CN and CF3COO) in a 2:1 ratio to give the 2:1 complexes, CuY(tcep)2. Single crystal X-ray structures show that for the anions X = Br and SCN, the complexes are coordination polymers, [CuX(tcep)]n, with the Cu centres being bridged by the anion, and as well, one nitrile arm per tcep ligand coordinates intermolecularly to the Cu to give tetrahedral ‘PBr2N’ and ‘PSN2’ coordination spheres respectively. The 2:1 compounds exhibit a variety of structures. For Y = ClO4, CN and CF3COO polymeric structures are formed except for Y = BH4 where the compound is a discrete monomer, [Cu(BH 4)(tcep)2], with a chelating anion and two monodentate P-bound tcep ligands. Both the compounds obtained with Y = CN and CF 3COO also contain coordinated anions and are formulated as [Cu(CN)(tcep)2]n and [Cu(CF3COO)(tcep) 2]n respectively. In the case of Y = CN the anion is bridging and the tcep ligands are only P-bound giving a ‘P2NC’ coordination sphere. In contrast, for Y = CF3COO, the anion is an O-bound monodentate and the tcep ligands bridge to give a ‘P2NO’ environment for the copper. In the case of Y = ClO4, the anion is not coordinated but a polymeric structure, [Cu(tcep)2] n(ClO4)n, is formed via bridging tcep ligands linking Cu centres intermolecularly resulting in a ‘P2N2’ coordination sphere.

Electrochemical deposition of p-type CuSCN in porous n-type TiO2 films

We present an energy band model and a method for filling p-type CuSCN in n-type porous TiO2 film. The energy band model is based on the interface energy levels between TiO2/CuSCN heterojunction and the aqueous electrolyte. The whole deposition process is divided into three stages: the uniform nucleation on the internal surface at positive potential, the crystal growth with the cathodic potential shifting negatively and the thermal activated growth at constant potential. This was demonstrated by the electrochemical experiment combining the hydrothermal process. It was found that the obtained TiO2/CuSCN heterojunction exhibited good rectification characteristics, indicating that an intimate electrical contact was formed between the large internal surface of TiO2 film and CuSCN. This novel hydrothermal-electrochemical method may be valuable for fabricating extremely thin absorber (eta)-solar cells and other semiconductor devices.
