Process and technological flux cobalt recovery. Part one [articol]

Abstract

The purpose of researches was to establish the optimum conditions in the cleaning process of a waste water with Co content and to retrieve the metal (Co) in form of crystalline CoC2O4·3H2O. It had been studied parameters like: the pH,the optimal dose of reagent precipitant, the cobalt concentration and the temperature. For this study were used analysis methods like chemical, spectral and thermic analysis. Basis on the experimental data we obtained a cobalt recovery degree of 99,3 %.
