AYALA B., Claudio; GALLARDO A., José  e  OLIVARES A., Manuel. Development of a copper concentration on-line Analyzer, for aqueous solutions from the Solvent Extraction process, through images processing and colorimetry. RISTI [online]. 2017, n.24, pp.1-12. ISSN 1646-9895.  http://dx.doi.org/10.17013/risti.24.1–12.

This article proposes a new analyzer, instrument to measure on line copper concentrations in aqueous. Its operating principle is based on technics of images processing and colorimetry, and an automated system for the taking of samples directly withdrawn from the process. In principle, this analyzer has been developed for the solvent extraction process, which is one of the stages of the hydrometallurgical process to obtain copper cathodes. The results of this development are promising due to the analyzer presents an acceptable precision for this type of non conventional instruments, remaining even a space for improvements when using components in its industrial version, of greater quality and robustness. With this new analyzer, the mining companies will have an alternative to measure on line this important operational variable, improving, with its application, the operation of the plant and increasing its efficiency and recovery

Palavras-chave : Analyzer; concentration; copper; extraction; solvent.
