Title: Ludwig Gemmer: Innovator in Gold Extraction and Comminution Technologies
Introduction
Ludwig Gemmer is a notable inventor based in Cologne, Germany. He has made significant contributions to the fields of gold extraction and comminution technologies. With a total of 2 patents, his work focuses on improving efficiency and reducing costs in these processes.
Latest Patents
Gemmer's latest patents include a method and installation for extracting gold from gold ore. This invention relates to a method and apparatus that save capital and operating costs in the extraction of gold. The process involves comminution and leaching of the ore, specifically reducing costs for ore grinding while maintaining gold yield during leaching. The gold ore is subjected to product bed stressing and interparticle crushing in the nip of a high-pressure roller press before leaching. The resulting product is then agglomerated and piled on a heap that is sprayed with a lixivium.
Another significant patent is a method and apparatus for continuous pressure comminution of brittle materials, such as cement clinker. This invention allows for simultaneous operations of unit grain comminution and product bed comminution within the same roller machine. The grinding stock is first precomminuted in a wider roller gap and then further comminuted in a narrower roller gap. This continuous pressure comminution is characterized by high pressure exceeding 2 metric tons per centimeter of roller length, with a sifter provided after the pressure roller.
