The solvent extraction separation of molybdenum and copper from acid leach residual solution of Chilean molybdenite concentrate
A procedure for recovery and separation of molybdenum (VI) and copper (II) from acid leaching residual solution of Chilean molybdenite concentrate by solvent extraction is studied. The process for the recovery of metals ...
Reverberatory furnaces in the Puna of Jujuy, Argentina, during colonial times (from the end of the 16th to the beginning of the 19th century A.D.)
(Academic Press Inc., 2017-12)
This paper presents the study of the extractive metallurgical technology that was employed in four colonial mining-metallurgical sites in the high plateau (Puna) of Jujuy, Argentina, dedicated to silver exploitation during ...
ON THE SYNTHESIS OF INORGANIC CHEMICAL AND METALLURGICAL PROCESSES. REVIEW AND EXTENSION
(PERGAMON-ELSEVIER SCIENCE LTD, 1999)
A review and extension of process synthesis principles to inorganic chemicals and extractive metallurgical operations is presented. It is shown that the conceptualization of extractive metallurgy and inorganic chemical ...
Optical Classification Of Quartz Lascas By Artificial Neural Networks
(TAYLOR & FRANCIS INCPHILADELPHIA, 2015)
Environment mapping for mobile robots navigation using hierarchical neural network and omnivision
Autonomous robots must be able to learn and maintain models of their environments. In this context, the present work considers techniques for the classification and extraction of features from images in joined with artificial ...
Fundamental aspects of sintering of chromites concentrates
Brazilian chromite ores need to be crushed to a size below 1 mm to allow concentrations that decrease the content of gangues. The concentrate particle size distributions therefore are not favourable for sintering. The ...
Hornos, minerales y escorias: una aproximación a la metalurgia extractiva en la Puna de Jujuy en época prehispánica y colonialFurnaces, minerals and slags: an approximation to extractive metallurgy in the puna of jujuy during pre-hispanic and colonial times
(Universidad de Buenos Aires. Facultad de Filosofía y Letras, 2014-06)
Se presentan los resultados de los análisis arqueométricos realizados sobre escorias recuperadas en seis sitios arqueológicos de la Puna de Jujuy (Argentina), uno probablemente de época prehispánica tardía y los otros cinco ...
Optimizing open-pit block scheduling with exposed ore reserve
(Southern African Inst Mining Metallurgy, 2016-07)
A crucial problem in the open pit mining industry is to determine the optimal block scheduling, defining how the orebody will be sequenced for exploitation. An orebody is often comprised of several thousand or million ...
In situ mining through leaching: experimental methodology for evaluating its implementation and economic considerations
(The Southern African Institute of Mining and Metallurgy, 2015)
Rising costs in the mining industry have necessitated a search for alternative methods for the recovery of metals from deposits that are no longer economically or environmentally exploitable by conventional mining. These ...
