Title: The Innovative Contributions of Leslie R. Tate
Introduction
Leslie R. Tate is a notable inventor based in Florence, Alabama, recognized for her significant contributions to the field of chemical engineering. With a total of 4 patents, she has developed innovative methods that enhance the recovery of valuable resources from industrial processes.
Latest Patents
One of her latest patents focuses on uranium recovery from wet-process phosphoric acid. This method involves treating the acid with a mixture of an ammonium salt or ammonia, a reducing agent, and a miscible solvent. The process allows for the separation of solids from the phosphoric acid liquid phase, resulting in a solid mixture of metal phosphates and uranium. The solid is then washed free of adhering phosphoric acid, dried, and dissolved in acid to recover uranium from the solution. Additionally, the miscible solvent and water are distilled away from the phosphoric acid, with all miscible solvent being recovered for recycling.
Another significant patent by Leslie R. Tate is the preparation of dicalcium phosphate from phosphate rock. In this method, the rock is treated with a mixture of water, carbonyl, and sulfur dioxide. Solids are separated from the liquid phase, and the solid phase consists of gangue and calcium α-hydroxysulfonate. Carbonyl and part of the sulfur dioxide are recovered from the solid through low-temperature thermal decomposition, while dicalcium phosphate is precipitated from the liquid phase by partial distillation of SO₂. All carbonyl is also recovered for recycling.
