Abstract

The invention belongs to the technical field of in-situ leaching uranium mining experimental equipment, and particularly relates to an in-situ leaching uranium mining full-process circulation experimental device. A constant-speed constant-pressure double-cylinder pump is connected with a high-pressure test column through a leaching agent liquid inlet valve, wherein a column leaching port pressureregulating valve is arranged at an outlet of the high-pressure test column; the column leaching port pressure regulating valve is connected with the upper part of an ion exchange column after passingthrough a leaching agent liquid outlet valve; the lower part of the ion exchange column is connected into a liquid collecting tank through an adsorption tail liquid valve; the liquid collecting tank is connected to a stirring tank through a reciprocating plunger pump and a liquid collecting valve; an oxygen steel cylinder is connected to the stirring tank through an oxygen pressure regulating valve, an oxygen flow controller and an oxygen one-way valve; a carbon dioxide steel cylinder is connected to the stirring tank through a carbon dioxide pressure regulating valve, a carbon dioxide flow controller and a carbon dioxide one-way valve; the stirring tank is connected to the constant-speed constant-pressure double-cylinder pump through a liquid distribution valve; and the column leaching port pressure regulating valve is connected to the liquid collecting tank through a leaching liquid non-adsorption valve. The whole equipment process is a process circulation process, only transparent pipelines need to be checked and replaced at regular intervals, and operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of experimental equipment for uranium mining by in-situ leaching, and in particular relates to a full-process circulation experimental device for uranium mining by in-situ leaching. Background technique [0002] The existing in-situ leaching uranium column leaching experiment device can only complete the leaching experiment without resin adsorption experiment, and the leaching solution cannot be recycled. As a result, the process of in-situ uranium extraction cannot be truly simulated. Usually there is no accumulation of impurity ions during acid column leaching, and the results of indoor experiments are better than those of field experiments; CO 2 +O 2 HCO of complexed uranium in leaching solution during column leaching 3 - Ions cannot be accumulated, and the results of indoor experiments are worse than field experiments, resulting in CO 2 +O 2 In column leaching experiment, the leaching liquid-solid r...
