Title: The Innovative Journey of Ernst Bareuther

Introduction

Ernst Bareuther, a notable inventor based in Butzbach, Germany, has made significant contributions to the field of industrial chemistry through his innovative patents. With a total of two patents to his name, Bareuther's work predominantly focuses on advancements in material processing and extraction methods.

Latest Patents

One of Bareuther's latest patents is a groundbreaking process for preparing a meta-kaolin white pigment from kaolinite. This innovative method involves the use of a fluidized bed reactor, where fuel, oxygen-containing gas, and kaolinite—containing water of crystallization—are combined. The kaolinite utilized in this process has particle sizes predominantly ranging from 0.1 to 3 mm. By forming a fluidized bed at elevated temperatures between 850 to 950 degrees Celsius, a meta-kaolin white pigment with minimal water of crystallization (not exceeding 2% by weight) is successfully produced.

Additionally, Bareuther developed a method for extracting gold and silver from ore. In this method, gold and/or silver is leached from comminuted ore using an alkaline cyanide lixiviant under superatmospheric pressure of at least 25 bar. The introduction of high-purity oxygen (at least 90% pure) significantly enhances the efficiency of the leaching process, resulting in reduced residence time while achieving high yield.

Career Highlights

Throughout his career, Bareuther has collaborated with prominent companies, including Metallgesellschaft Aktiengesellschaft and Vereinigte Aluminum-werke Aktiengesellschaft. His expertise and innovative mindset have made him a valuable asset in the industry, contributing uniquely to various projects focused on chemical processes and materials.
