Patent number: 11123772Abstract: Differences in x-ray absorption coefficients and ash content are used to process coal waste and concentrate rare earth elements (REE) found in coal seams. A method for processing the coal waste includes receiving, by a detector, at least one collimated x-ray beam from an x-ray source that has been passed through a sample of coal waste; determining measurements of at least one x-ray absorption characteristic of the sample based on the received at least one collimated x-ray beam; and identifying a first region in the sample having a concentration of rare earth elements based on the measured x-ray absorption characteristic.Type: GrantFiled: May 22, 2019Date of Patent: September 21, 2021Assignee: Mineral Separation Technologies, Inc.Inventors: Charles E. Roos, Edward J. Sommer, Jr., Charles D. Roos, Ricky Q. Honaker, Aaron Noble

Patent number: 9126236Abstract: Disclosed herein is the use of differences in x-ray linear absorption coefficients to process ore and remove elements with higher atomic number from elements with lower atomic numbers. Use of this dry method at the mine reduces pollution and transportation costs. One example of said invention is the ejection of inclusions with sulfur, silicates, mercury, arsenic and radioactive elements from coal. This reduces the amount and toxicity of coal ash. It also reduces air emissions and the energy required to clean stack gases from coal combustion. Removal of said ejected elements improves thermal efficiency and reduces the pollution and carbon footprint for electrical production.Type: GrantFiled: July 2, 2014Date of Patent: September 8, 2015Assignee: Mineral Separation Technologies, Inc.Inventors: Charles E. Roos, Edward J. Sommer, Jr.

Patent number: 9114433Abstract: Disclosed herein are methods of sorting coal into multiple fractions based upon x-ray absorption and size characteristics in order to remove rocks and other contaminants of various sizes from coal. The use of such dry processing of coal is desirable as it reduces pollution and transportation costs. The multi-fractional sorting of coal is a more efficient manner for identifying and removing rock and contaminants from coal.Type: GrantFiled: January 15, 2013Date of Patent: August 25, 2015Assignee: Mineral Separation Technologies, Inc.Inventors: Charles E. Roos, Edward J. Sommer, Jr., Charles D. Roos
