Hugues Menard

Title: Hugues Menard: Innovator in Environmental Chemistry

Introduction

Hugues Menard is a notable inventor based in Sherbrooke, Canada. He has made significant contributions to the field of environmental chemistry, particularly in the removal of hazardous substances from industrial processes. With a total of 6 patents to his name, Menard's work focuses on innovative methods for treating toxic materials.

Latest Patents

One of Menard's latest patents is for the electrochemical removal of dissociable cyanides. This method provides a means of destroying highly stable metal cyanide ions found in solutions, converting them into harmless by-products. Unlike conventional methods that merely complex the cyanide into removable forms, Menard's approach effectively destroys the cyanide present in the sample. The invention involves creating a highly alkaline solution containing metal cyanide ions and subjecting it to electro-oxidation.

Another significant patent is for a process that removes and recovers copper, silver, and zinc from sulfide ores. This innovative treatment utilizes a solution of sulfurated sulfite ions and ammonium ions to extract most metals from sulfide ores. The resulting gold-bearing ores become more amenable to cyanide extraction. Dissolved metals are reclaimed through techniques such as electrowinning or liquid-liquid extraction, while the sulfurated sulfites and ammonia solution is recycled for further processing of fresh ores.

Career Highlights

Throughout his career, Hugues Menard has worked with various organizations, including Ug Plus International Inc. and L'Institut De L'Amiante. His expertise in environmental chemistry has allowed him to develop methods that not only enhance metal recovery but also minimize environmental impact.
