Title: Eduardo Balladares Varela and a Waste-Free Copper Production Method.
Introduction
Eduardo Balladares Varela is an inventor associated with Concepción, Chile, and Universidad de Concepción. His patent describes a process for producing copper metal from copper concentrates while avoiding waste generation.
Latest Patents
The provided information lists 1 patent for Balladares Varela: “Method for Producing Copper Metal from Copper Concentrates Without Generating Waste.” The method oxidizes copper concentrate, cleans and cools the resulting gases, and feeds material into a reduction reactor. It then processes the gases, discharges hot powders and calcines into water, and separates the magnetic fraction. Subsequent steps thicken and filter materials, float silica and inert substances, and recover a final concentrate containing copper and noble metals for smelting. Ground smelt slag is recirculated to a roasting reactor.
Career Highlights
Balladares Varela’s listed invention focuses on integrating material recovery and slag recirculation into copper production. The process is designed to recover valuable metals while returning ground smelt slag to the roasting stage.
Collaborations
His listed coworkers include Igor Wilkomirsky Fuica and Roberto Parra Figueroa. The provided information associates Balladares Varela with Universidad de Concepción.
Conclusion
Eduardo Balladares Varela’s patent presents a copper-production process that combines metal recovery, material separation, and slag recirculation in an effort to avoid generating waste.
