Abstract There are only a few smelters processing copper concentrates directly into blister copper. Despite the many advantages of this process, serious challenge technology is need to process resulting flash smelting slag. It contains 12–15% and 2.5–4% lead. In form, it cannot be considered as waste material and, therefore, high-temperature reduction carried out. This decopperization energy- t...

<span lang="EN-US">Lithium ion batteries have been widely applied in portable electronic devices and electric vehicles as high-density energy storage. The significant consumption of lithium is outweighed by the threat to environment battery waste. Recovery valuable metals contained batteries, such Cu foil, one efforts overcome environmental pollution due copper metal. hydrometallurgical m...

In this work, two hydrometallurgical processes for gold recovery are explored a small-scale mining case study located at Ponce Enriquez, Azuay, Ecuador. The systems consider the use of sodium cyanide and thiosulfate as leaching agents, with without incorporation subsystem residual mercury removal. proposed modelled using commercial simulator PRO/II interconnected Python scientific computing env...
