Environmental impact of increasing production of gold from hydrothermal resourcesydrometallurgical processes of pressure and biological oxidation..The paper demonstrates how technological developments have not only been driven by the normal quest for lower costs and higher recoveries, but in this case by consideration for plant safety and the environment. The modern plant is con

leaching recovery of copper: what’s next?l research and engineering effort is being expended to recover copper from oxide ores. However, the greatest potential for copper ISL extraction remains with the deep seated deposits that would otherwise be left unmined by conventional methods..This paper highlights some historical aspects of copper

Multicomponent equilibrium calculations in process design: study of some acid digester reactorsnetics. In that case the minimization algorithm results with a close to equilibrium approximation..The advantage of the thermodynamic algorithm is the possibility to follow both the chemical composition of all reactor phases and the energy balance of the reactor. Thus the calculation results can be

Hydrothermal precipitation from aqueous solutions containing iron(III), arsenate and sulphatetaining high concentrations of iron and this can readily incorporate substantial amounts of arsenic..The relative order of stability (based on arsenic solubility) of the compounds synthesised at elevated temperatures is: Type-2 003D; Scorodite > Arsenical Ferrihydrite > Type-1. When a comparison is

Scope and limitations for application of selectivity in oxidation potential-controlled leaching of mespect to copper can be achieved, according to the simplified metathesis reaction MeS + CuCl. → MeCl. + CuS.Thereby, the cupric/cuprous chloride leach solution can be regenerated from the covellite formed by oxidation with CI. or HC1 and O...In the case of a matte, the selective leaching and regener

Electrochemical study of oxidative dissolution of synthetic violarite in aqueous mediaetween the bulk aqueous solution and the mineral surface. However, the oxidation involves an intrinsically slow electron transfer for the S, Fe., Ni. / FeNi.S. couple with heterogeneous rate constant, k. = 10. m s.. Within the potential range relevant to iron(III) chloride leaching, this electron tr
