(Universidad Nacional de Misiones. Facultad de Ciencias Exactas, Químicas y Naturales. Centro de Investigación y Desarrollo Tecnológico, 2014-02)
Fundiciones 2, Rinconada, Jujuy, instalación metalúrgica probablemente de finales del siglo XVIII, consta de dos recintos adosados, un refugio techado y cinco hornos de reverbero, tres de los cuales se encuentran dentro ...
AN INTEGRATED APPROACH TO THE LONG-TERM PLANNING PROCESS IN THE COPPER MINING INSDUSTRY
Long-term mine-metallurgy planning in the copper mining industry is a complex process that simultaneously establishes ore extraction policies for multiple mines, an investment plan, and an operating plan for processing ...
Methodology for evaluation of mud rush risk in block caving mining
(Southern African institute mining metallurgy, 2017)
Mud rushes are sudden inflows of fine wet ore within underground mines; they can harm people and equipment as well as cause production delays. Block and panel caving mines are prone to mud rushes in their production levels, ...
Geotechnical characterization of ore related to mudrushes in block caving mining
(South African Institute of Mining and Metallurgy, 2017)
Mudrushes are sudden inflows of mud ore into underground miningfacilities. They may cause harm to people and equipment, productiondelays, dilution of ore, and mine closure. The aim of this work is to charac-terize, by ...
Characterization of Slags Produced During Gold Melting Process
In the extractive metallurgy of gold ores the cyanidation and melting processes are generally applied. These processes allow obtaining the “dore”. The slag generated during the melting process presents various characteristics, ...
Zinc Recovery from Spent Chemical Sorbent by Dry Chlorination and Electrodeposition from Chloride Solutions
(SCIENCEDOMAIN international, 2017-01)
Spent catalysts, chemical traps and sorbents are types of solid wastes generated worldwide, which contain potentially valuable or environmentally hazardous materials that need to be recovered before final deposition. ...
Fluidity on Metallic Eutectic Alloys
Columnar-to-Equiaxed Transition in Metal-Matrix Composites Reinforced with Silicon Carbide Particles
(Hindawi Corporation, 2013-12)
The present work is focused on the study of the effect of directional heat extraction on the silicon-carbide (SiC) distribution in zinc-aluminum matrix composites (MMCs) and on the columnar-to-equiaxed (CET) position in ...
