This study aims to evaluate and compare each other, surface-active additives on the inhibition and control of acid mist, as well as different control parameters and operation of the copper electrowinning process, such as surface tension electrolyte effect on current efficiency, energy consumption and cathode quality. The results obtained confirm that the commercial additive Fluoride FC-1100 is an excellent surfactant, and that low doses drastically reduced the surface tension of electrolyte (from 75 dynes / cm to 55 dynes / cm) and therefore allows to reduce acid emissions without interfere with other process parameters such as current efficiency, energy consumption or cathodic quality deposits and obtaining good adhesion. This is not the case of Genapol PF-10, drastically reduces the surface tension and hence the mist generation but shows a detrimental effect on the current efficiency d...
