TH495EX - Procedures for uranium recovery using alkyl pyrophoric acid. And alkaline solution for cleaning - Google Patents

Abstract

Wet process uranium recovery from phosphoric acid. Contains the use of an alkyl pyrophosphoric acid extractor, the extractor also contains a modifier for helping alkyl pyrophosophils. Aric acid esters are a solution in organic diluents that It is considered not mixed with water when extracting uranium from an acid-produced acid. Wet process Therefore, the APPA extractor reacts with oxidizing agents such as hydrogen peroxide and purifies the urea. Smooth into an alkaline solution for washing, alkaline solution for washing, as a solution in water of metal, alkali or ammonium carbonate or hydroxide extractor. Without being extracted to be returned to contact with the acid produced With a new wet method Which ferric iron contained it was dropped? The sediments in the rinsing solution were separated from the recovery solution, dehydrated uranium, and calcine. Will get the product U3O8

Claims (1)

1. A process for purifying uranium from organic extracts with extracts. Which is composed of alkyl pyrophosphoric acid Soluble in organic diluents which can be regarded as not mixed with water, such organic extracts contain tetravalent uranium and modifiers, which are alcohol or phenol. Enough Will preserve alkyl pyrophosphoric acid to remain a solution in Such diluents during cleaning, assembly processes Together with the addition of oxidizing agents to the said intrinsic extract To oxidize tetravalent uranium, and purify
