Flow uranium leaching system and flow uranium leaching process

Abstract

The invention discloses a flow uranium leaching system and a flow uranium leaching process. The flow uranium leaching system comprises a liquid dispensing tank, a flow uranium leaching tank, a primary liquid slot, an adsorption tower, a tail liquid slot, an oxidization slot and a communication pipeline, wherein the outlet of the liquid dispensing tank is communicated with a leaching solution inlet in the bottom of the flow uranium leaching tank; the liquid outlet in the upper part of the tank body of the flow uranium leaching tank is communicated with the primary liquid slot; the primary liquid slot is communicated with the inlet of the adsorption tower; the outlet of the adsorption tower is communicated with the tail liquid slot and the liquid dispensing tank; the tail liquid slot is communicated with a culture solution dispensing slot; one path of the outlet of the culture solution dispensing slot is connected to the liquid dispensing tank through an oxidization slot; and the other path of the outlet is communicated with the liquid dispensing tank. According to the invention, the flow uranium leaching system is adopted to replace strong acid used in the past, to strength an oxidant, and to prolong the soaking time, so that the uranium leaching efficiency can be improved, and therefore, the conventional batch type tank and pile type uranium leaching process is changed into a continuous uninterrupted flow uranium leaching process, and good effect is achieved.

Description

technical field [0001] The invention belongs to the field of uranium smelting, and relates to a high-efficiency uranium leaching system for avoiding precipitation compaction, in particular to a flow uranium leaching system and a flow uranium leaching process suitable for hard rock uranium ore. Background technique [0002] With the development of nuclear power energy, the requirements for nuclear fuel will exceed the current development level of uranium resources. Due to the high cost of uranium smelting in the traditional water smelting process, it is only suitable for high-grade uranium ores. Therefore, most uranium mines in southern my country that mainly use hard rock have turned to heap leaching and pool leaching for uranium mining. host. However, the heap leaching and pool leaching uranium mining cycle is long, and it is difficult to meet the growing demand for uranium metal in nuclear power. What's more serious is that many uranium mines that mainly use heap leaching...

Problems solved by technology

However, the cycle of heap leaching and pool leaching for uranium is long, and it is difficult to meet the growing demand for uranium metal in nuclear power.

What's more serious is that many uranium mines that mainly use heap leaching and pool leaching uranium mining devices still have losses. The more they produce, the more they lose. This has become a hindrance to the uranium mining industry in southern my country and seriously affects the uranium resources in our country. reliable supply
