Title: Innovations of Herbert E. Barner in Manganese Nodule Processing

Introduction

Herbert E. Barner, an inventive mind from Westford, MA, has made significant strides in the field of metallurgy through his pioneering patent work. With a career defined by innovation, Barner holds a total of two patents that focus on the efficient extraction and recovery of valuable metals from manganese nodules.

Latest Patents

Barner’s latest patents encompass advanced processes designed for the treatment and recovery of metals from manganese ore nodules. The first patent, titled "Two-stage fluid bed reduction of manganese nodules," outlines a method where manganese nodules are treated in a two-stage fluid bed process. Initially, these nodules are calcined using direct fuel injection in a controlled atmosphere, eliminating about half of their oxygen content. The subsequent stage involves reducing the calcined nodules with synthesis gas, making the metal values such as copper and nickel leachable through an ammonia-ammonium carbonate solution.

His second patent, "Elevated pressure operation in the cuprion process," enhances the recovery of copper, nickel, cobalt, and molybdenum. This process involves direct leaching of finely comminuted manganese nodules with an aqueous ammoniacal leach solution containing cuprous ions. By increasing the pressure of the reducing gas, the cuprous ions are regenerated more efficiently, thereby elevating the concentration within the reaction vessels. This improvement not only increases the overall efficiency of the process but also allows for a reduction in reactor size, showcasing Barner's innovative engineering capabilities.
