Detection of thiourea from electrorefining baths using silver nanoparticles-based sensors
(Elsevier Science Sa, 2015-01)
A novel and easy-to-use colorimetric thiourea (TU) sensor based on immobilized polyvinylpyrrolidone-stabilized silver nanoparticles (PVP-AgNPs) is reported. The new sensor is aimed for its direct application in copper ...
Forecasting copper electrorefining cathode rejection by means of recurrent neural networks with attention mechanismForecasting 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 ...
Electrochemical sensor for thiourea focused on metallurgical applications of copper
(Elsevier Science Sa, 2016-09)
A simple and reliable device is presented for the direct monitoring of thiourea in copper electrorefinery baths as a tool for reconditioning of industrial baths, and so reducing its environmental impact. For this purpose, ...
Some recent developments in the electrorefining and electrowining of copper - [Boletín G 1]
(Instituto Geológico, Minero y Metalúrgico - INGEMMETPE, 1980)
En vista de la necesidad de minimizar los costos de producción en la electrorefinación y electro deposición de cobre, se ha considerado varios ensayos. Estos incluyen burbujeo de gas, corriente periódica reversible, ...
