Title: Fernando Antonio Parada Luna and Waste-Free Copper Production

Introduction

Fernando Antonio Parada Luna is an inventor associated with Universidad de Concepción in Concepción, Chile. His patent work addresses copper processing, with a method designed to recover copper and valuable metals while avoiding waste generation.

Latest Patents

Parada Luna is associated with 1 patent: “Method for Producing Copper Metal from Copper Concentrates Without Generating Waste.” The process oxidizes copper concentrate, cleans and cools the resulting gases, and feeds material into a reduction reactor. It then cleans the gases and discharges hot powders and calcines into water.

The method continues with magnetic separation, followed by thickening and filtering the magnetic fraction. Silica and inert materials are separated by flotation, then thickened and filtered. The final concentrate, containing copper metal and noble metals, is also thickened and filtered before smelting. Ground smelt slag is recirculated to a roasting reactor, completing the process’s material-recovery cycle.

Career Highlights

The patent describes an integrated approach to copper production that combines gas treatment, reduction, separation, filtration, smelting, and slag recirculation. Its stated objective is to produce copper metal from concentrates without generating waste.

Collaborations

Parada Luna’s listed coworkers include Igor Wilkomirsky Fuica and Eduardo Balladares Varela. His association with Universidad de Concepción connects his work to an academic institution in Chile.

Conclusion

Fernando Antonio Parada Luna’s patent presents a copper-processing method focused on recovering copper and noble metals while recirculating smelt slag and minimizing waste.
