Tailing pond in-situ leaching liquid collection roadway mining technique and reaction device

Abstract

The invention discloses a tailing pond in-situ leaching liquid collection roadway mining technique which comprises the following steps: by virtue of an original impervious barrier of a tailing pond, laying a roadway at the lower part of the impervious barrier, carrying out anchor-plate retaining and anti-seepage measures upon the roadway, intermittently inputting and injecting a leaching solutioninto tailings to be treated, enabling the tailings to be naturally oxidized and reacted and exchanged with minerals, enabling a leaching liquid to flow into a liquid collection roadway along with an anchor rod hole, connecting liquid collection roadways in parallel by using a pipeline at ends of the liquid collection roadways, further enabling the leaching liquid to flow into a hydrometallurgy plant by virtue of roadway slope height differences, and carrying out water washing and smelting, thereby obtaining expected minerals. The technique is low in cost, small in repairing amount, simple to manage and small in leaching facility amount, has active functions in promoting reuse of tailings and alleviating resource shortage in China, is applicable to tailing ponds of large-size easy dump leaching mining, is not limited by dump site selection, and is rapid in investment outstanding, low in production cost and low in investment, and the leaching liquid can be recycled in time.

Description

technical field

[0001] The invention relates to the technical field of metal tailings leaching and smelting, in particular to a mining technology and a reaction device for in-situ leaching liquid collection roadway of a tailings pond. Background technique

[0002] The traditional utilization of tailings is mainly divided into two aspects: 1—the useful minerals are screened out from the tailings again, and the concentrate is smelted; Roads, etc.; 3—Store the tailings directly in specially built tailings ponds. At present, the third method is the most widely used tailings treatment method in most concentrators. However, the concept of tailings is relative. Under the previous technical level, some precious metals and rare metals could not be recovered, but with the development of science and technology, the useful components in tailings can be redeveloped and utilized, such as hydrometallurgy technology Recovery of valuable elements in tailings.

Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] In the embodiment of the present invention, an in-situ leaching liquid collection mining technology for tailings ponds uses the original anti-seepage layer of the tailings ponds to arrange a roadway at the lower part of the tailings pond, and implements bolting and shotcreting support and anti-seepage measures for the roadway. The tailings to be treated are intermittently injected with leaching solution to make it oxidize naturally and repl...
