In this work we studied the decomposition kinetics and cyanidation of the argentian lead jarosite in NaOH media.

The global cyanidation process consists of two stages: decomposition reaction followed by the instant cyanidation of the decompositionproducts. 2011 artículo científico 1870-249X https://www.redalyc.org/articulo.oa?id=47521272003 es http://www.redalyc.org/revista.oa?id=475 Journal of the Mexican Chemical Society application/pdf Sociedad Química de México Journal of the Mexican Chemical Society (México) Num.4 Vol.55 |
