Latest Patents

Reynier's latest patents include a "Combined grinding and leaching apparatus for ores and wastes and methods of use thereof." This invention discloses an attrition mill designed for grinding or comminuting ores, mine wastes, and radioactive wastes. The apparatus is capable of processing materials that may contain metals such as uranium, cesium, mercury, thorium, and rare earth elements. The methods associated with this patent involve grinding and mixing the ore or waste with a solid inorganic base and water, followed by leaching with an aqueous inorganic acid to solubilize the metals present.

Another significant patent is the "Process for metals leaching and recovery from radioactive wastes." This process outlines a method for recovering metals from solid radioactive waste, particularly focusing on uranium, cesium, mercury, thorium, and rare earths. The process includes a leaching step where the solid waste is contacted with an aqueous inorganic acid and a leaching salt, resulting in a metal-rich leachate and a metal-poor waste that are subsequently separated.
