Title: Aysan Molaei: Innovator in Copper Recovery Technology

Introduction

Aysan Molaei is a notable inventor based in Edmonton, Canada. He has made significant contributions to the field of metallurgy, particularly in the recovery of copper from sulphidic feed. His innovative approach combines various leaching processes to enhance efficiency and sustainability in copper extraction.

Latest Patents

Aysan Molaei holds a patent for an "Integrated pressure oxidative leach of copper sulphidic feed with copper heap leach." This patent describes a process for recovering copper from sulphidic feed that contains iron, arsenic, and copper. The method involves pressure oxidizing an aqueous feed slurry to create a liquid phase rich in free sulphuric acid and aqueous copper sulphate, while precipitating arsenic as solid iron arsenic compounds. The treated slurry is then separated, allowing for the recovery of copper from the liquid phase, which is subsequently neutralized in a copper heap leach to produce a pregnant leach solution (PLS) containing copper.

Career Highlights

Aysan Molaei is currently employed at Sherritt International Corporation, where he continues to develop and refine his innovative processes. His work focuses on improving the efficiency of copper recovery methods, which is crucial for the mining and metallurgy industries.
