Title: Tomokazu Tabata: Innovator in Uranium Recovery
Introduction
Tomokazu Tabata is a notable inventor based in Shinnanyo, Japan. He has made significant contributions to the field of uranium recovery, particularly through his innovative methods that enhance the extraction of uranium from phosphate rock.
Latest Patents
Tabata holds a patent for a method of recovering uranium. This method involves obtaining uranium values from phosphate rock by acidifying the rock, which contains uranium values and at least one other heavy metal, with a mineral acid. The process results in a crude acid, which is then solvent-extracted with an organic solvent to separate a raffinate from a relatively pure, wet process phosphoric acid. The raffinate is treated with a base to raise the pH to 1-2, leading to the coprecipitation of uranium hydroxide or phosphate and other heavy metal hydroxides or phosphates. The uranium content of the coprecipitate after drying is at least as high as 0.3%, comparable to that of the highest quality uranium ores.
Career Highlights
Tabata is associated with Toyo Soda Manufacturing Co., Ltd., where he has been instrumental in advancing technologies related to uranium recovery. His work has not only contributed to the field of mining and resource recovery but has also positioned his company as a leader in innovative solutions.
