Latest Patents
One of his latest patents is 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 process. The apparatus and process include comminution and leaching of the ore, significantly reducing costs associated with 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 product that has been comminuted and subjected to interparticle crushing is then agglomerated and piled on a heap that is sprayed with a lixivium.
Another significant patent is a method for the production of a coal suspension. This invention involves an apparatus and method for producing a free-flowing coal suspension with a high solids content. The coal is ground in at least two stages, utilizing a mill with a calibrating effect in one stage and a non-calibrating mill in another stage. A sub-quantity of viscosity-reducing additive is added to the coal before each grinding, eliminating the need for drying or reconcentration of the suspension.
