Title: Louis Joseph Nordrum: Innovator in Heavy Metals Recovery

Introduction

Louis Joseph Nordrum is a notable inventor based in Corte Madera, California, known for his contributions to the field of metal recovery from spent catalysts. With a total of two patents to his name, his work focuses on the innovative processes that enhance the efficiency of metal recovery, thereby addressing significant environmental challenges.

Latest Patents

His latest patents detail a Process for separating and recovering metals. This invention presents a method for treating spent catalysts that contain heavy metals, specifically targeting Group VIB and Group VIII metals. The process involves several intricate steps, beginning with the deoiling of the spent catalyst, which is subsequently treated with an ammonia leach solution. This treatment dissolves the target metals, forming a leach slurry, which undergoes solid-liquid separation to recover a leach solution. Following this, chemical precipitation and solids repulping are executed to yield an effluent containing ammonium sulfate (Amsul), ammonium sulfamate, and various metals from Groups VB, VIB, and VIII. The process also includes steps for sulfidation, oxydrolysis, and iron precipitation to ensure the removal of residual metals, achieving a stream with less than 10 ppm of Group VB and Group VIB metals.
