A contribution to the study of CuSO4 center dot 5H2O solubility in aqueousmedia

Pentahydrate copper sulphate (Blue vitriol) is a copper salt used in minera llurgy as activator reagent in concentration methods by flotation for sulph ide ores. In this work, crystallization conditions of copper sulphate solut ions have been determined as a function of both temperature and sulphuric a cidity. The results obtained showed that .Cu2+ concentration in the solutio n is mainly a direct function of the logarithm of temperature and the sulfu ric acid concentration. The influence of Zn2+ presence in copper sulphate s olubility has been also studied at ambient temperature. Results obtained le d to a multiple linear regression between CU2+ concentration in the solutio n and sulphuric acid and Zn2+ concentrations in the medium. Finally, a comp arison between the results obtained and data available in the literature is made.
