Recovery of silver from slags generated by melting precipitates from the Merrill–Crowe process
Autor: H. A. Moreno Casillas, Adriana Gamboa Hernández, J. R. Parga Torres
Publikováno v: Canadian Metallurgical Quarterly. 58:204-212
Slag that is produced from induction furnaces that use the Merrill–Crowe process still contains precious metals. In this study, a pyrometallurgical treatment was performed for their recovery in ord...

Recovery of Silver and Gold from Cyanide Solution by Magnetic Species Formed in the Electrocoagulation Process
Autor: Jesús L. Valenzuela, H. Moreno, M. Rodriguez, J. R. Parga, V. Vazquez
Publikováno v: Mineral Processing and Extractive Metallurgy Review. 33:363-373
Cyanidation is the predominant process by which gold and silver are recovered from their ores in metallurgical operations, and it is recognized that the Carbon in Pulp, the Merrill–Crowe, the Ion Exchange, and Solvent Extraction processes are used

Development of aluminum hydroxides in Al–Mg–Si/SiCp in infiltrated composites exposed to moist air
Autor: Hugo F. Lopez, M. Rodríguez-Reyes, J. R. Parga-Torres, J.L. Acevedo-Dávila, Martin I. Pech-Canul, M. Sanchez-Araiza
Publikováno v: Ceramics International. 37:2719-2722
In this work the degradation of metal/composite interfaces (M/C) in Al–Mg–Si/SiC p composites exposed to moist environments was investigated. The formation of Al(OH) 3 at the M/C interface indicated the development of Al 4 C 3 during processing.

Thermodynamic Studies of the Arsenic Adsorption on Iron Species Generated by Electrocoagulation
Autor: H. Moreno, V. Vazquez, J. R. Parga
Publikováno v: Journal of Metallurgy. 2009:1-9
Protection of global environment and sustainable sources of clean water are a necessity for human survival. The wide use of heavy metals by modern industries has generated heavy metals containing wastes and by-products. Specifically, large quantities

Bacís flotation cell for gold- and silver-beard pyrite recovery
Autor: Jesús L. Valenzuela, J. R. Parga, Salvador Aguayo
Publikováno v: Scopus-Elsevier
In mineral processing, poor froth-flotation performance translates into both an enormous loss of revenue and an unnecessary waste of the ore reserve. In this context, Bacis Mining Company developed a versatile new, high-performance flotation-cell des
