Title: Richard G. Sandberg: Innovator in Manganese Processing
Introduction
Richard G. Sandberg is a notable inventor based in Gloucester, VA (US). He has made significant contributions to the field of manganese processing, holding a total of 2 patents. His innovative approaches have the potential to enhance the efficiency of metal extraction from manganese oxide ores.
Latest Patents
Sandberg's latest patents include methods for refining manganese oxide ores. The first patent describes a process that treats manganese oxide ores in an aqueous medium using hydrogen halide or sulfuric acid, along with hydrogen sulfide or a metal sulfide. This method allows for the separation of a leach liquor containing desirable metal halides from the solid, insoluble residue. Notably, any iron present in the ores is either not dissolved or converted to an insoluble iron oxide, while elemental sulfur is also obtained. The recovery of metal values from the leach liquor is achieved through crystallization of manganese halide and liquid ion exchange extraction of other metal values.
The second patent focuses on the halidation of nonferrous metal values in manganese oxide ores. This process involves reacting the ore with an aluminum halide or a ferric halide at elevated temperatures, typically above 50 degrees Celsius, and preferably above 130 degrees Celsius. The manganese oxide ore can be treated with or without reduction, and if reduction is desired, it can occur prior to or simultaneously with the reaction. The resulting nonferrous metal halides can be separated from the reacted ore residue using conventional methods such as leaching or evaporation.
