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

Embodiment 1

[0069] A mobile uranium leaching system, such as figure 1 -3 shows that it includes a liquid distribution tank 1, a flow uranium immersion tank 2, a stock solution tank 3, an adsorption tower 4, a tail liquid tank 5, a culture solution distribution tank 12, an oxidation tank 6, a liquid pump 7, a flow meter 8 and connected pipes.

[0070] The leaching solution of the flowing uranium leaching pool 2 enters from the bottom and exits from the top. The height of the flowing uranium leaching pool is 360 centimeters, and the liquid outlet 23 is set at a height of 330 centimeters in the flowing uranium leaching pool. The liquid inlet system includes a leaching solution inlet 24, a cloth The liquid pipe 22 and the pebble layer, four immersion liquid inlets 24 are evenly arranged at the bottom of the pool body, in order to maintain the balance of the liquid inlet pressure, the immersion liquid inlet 24 is externally connected to the liquid inlet pipe 21, internally connected to the liq...

Abstract

The invention discloses a flow uranium leaching system and a flow uranium leaching process. The flow uranium leaching system includes a liquid distribution tank, a flow uranium leaching tank, a raw liquid tank, an adsorption tower, a tail liquid tank, an oxidation tank and a connecting pipeline, and the liquid distribution tank The outlet is connected with the leaching liquid inlet at the bottom of the mobile uranium leaching pool, the liquid outlet provided on the upper part of the mobile uranium leaching pool is connected with the raw solution tank, the raw solution tank is connected with the inlet of the adsorption tower, and the outlet of the adsorption tower is connected with the tail liquid tank It is connected to the liquid distribution tank, the tail liquid tank is connected to the culture liquid distribution tank, the outlet of the culture liquid distribution tank is connected to the liquid distribution tank through the oxidation tank, and the other is connected to the liquid distribution tank. The invention adopts the flow uranium leaching system to replace the traditional use of strong acid, strengthen the oxidant and prolong the immersion time to improve the efficiency of uranium leaching, and changes the traditional batch pool and heap uranium leaching process into continuous uninterrupted flow uranium leaching, achieving good effect.

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...
