Modelo técnico e econômico de reaproveitamento de placas de circuito impresso
(Universidade Tecnológica Federal do ParanáCuritibaBrasilDepartamento Acadêmico de MecânicaEngenharia MecânicaUTFPR, 2012-10-24)
Due to the accelerated development of new products and technologies and the planned obsolescence of consumer goods, electronic products are discarded increasingly earlier than expected, which creates the problem of proper ...
Análisis de factibilidad técnica del proceso pirometalúrgico para reciclaje de baterías de vehículos con motores eléctricos en Ecuador
(2019-04)
This document consists an analysis to determine the technically feasible to create a recycling plant for lithium-ion and nickel-metal hydride batteries using the pyrometallurgical process in order to reduce the environmental ...
Kinetic aspects on ferric arsenate formation in a fix bed gas-solid reaction system
(Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas., 2015-01-01)
The fixation of arsenic contained in gases produced during pyrometallurgical processes by using solid ferric oxide was studied in the range 873-1073 K under different oxygen potential and solid aggregates porosities. Arsenic ...
Modelamiento cinético del procesamiento de minerales lateríticos de níquel por vía pirometalúrgica
(2016)
Con el fin de estudiar el comportamiento de minerales lateríticos cuando son sometidos a procesos pirometalúrgicos como el proceso Rotary Kiln Electric Furnace (RKEF), se trabajaron tres muestras con contenidos de níquel ...
Forecasting copper electrorefining cathode rejection by means of recurrent neural networks with attention mechanism
(2021)
Electrolytic refining is the last step of pyrometallurgical copper production. Here, smelted copper is converted into high-quality cathodes through electrolysis. Cathodes that do not meet the physical quality standards are ...
Estudo de caso e aplicação do MASP em uma indústria de baterias de chumbo-ácido
(Universidade Tecnológica Federal do ParanáFrancisco BeltraoBrasilEngenharia de ProduçãoUTFPR, 2020-02-19)
Currently, Brazil has a small portion of lead reserve, a situation that leads battery manufacturers to seek new alternatives to keep their product competitive in the market. One of the alternatives is the recycling of ...
Data Fusion of Laser-Induced Breakdown Spectroscopy and Spectral Reflectance Techniques for Estimating the Mineralogical Composition of Copper Concentrates
(2021)
The pyrometallurgical copper industry faces some challenges in terms of the instrumentation
for its processes. In this work, Laser-Induced Breakdown Spectroscopy (LIBS) data will
be studied and combined with Diffuse ...
Thermogravimetric Study of Porous Forsterite Synthesis by Hydromagnesite and Silica Gel Chlorination
(Springer, 2019-06)
A novel pyrometallurgical process for the synthesis of porous forsterite by calcination in chlorine of a mixture containing hydromagnesite and silica gel was developed. The aim of this work was to produce porous forsterite ...
