Title: Innovations by Inventor Mohamed Buarzaiga
Introduction
Mohamed Buarzaiga is a notable inventor based in Mississauga, Canada. He has made significant contributions to the field of nickel processing, holding 2 patents that focus on innovative methods for producing nickel hydroxide and removing manganese from nickel laterite waste liquors. His work has implications for both environmental sustainability and industrial efficiency.
Latest Patents
Buarzaiga's latest patents include a process for producing nickel hydroxide suitable for pelletization with iron-containing ore and for stainless steel manufacture. This process involves treating a nickel-containing leach solution with a base to form a slurry, which is then thickened and filtered. The resulting filter cake is washed and treated with acid to produce a concentrated nickel-containing solution. This solution undergoes solvent extraction to remove impurities, resulting in a purified nickel hydroxide precipitate.
Another significant patent is a method for removing manganese from nickel laterite waste liquors. This method aims to reduce manganese concentration to less than about 1 mg/L without precipitating significant amounts of magnesium. The process utilizes three separate circuits to achieve the desired manganese levels, employing pH adjustments and oxidative precipitation techniques.
