Embodiment 1

[0020] The processing method of a kind of metal tailings slag of the embodiment 1 of the present invention, it is to carry out with the gold tailings slag that existing gold mining enterprise produces in the production process as the object, and its processing method comprises the following steps of implementing: The metal tailings slag produced in the process is collected and pretreated to remove large particles and impurities, and the precious metals contained in the metal tailings slag are re-extracted through a series of new extraction methods and special equipment. In the precious metal process, the ore powder collected by the air volume specific gravity separation product is used as clinker for cement production to produce cement.

[0021] The process for extracting precious metals mentioned above is to dry the gold tailings slag, use the instantaneous high temperature generated by electron collision to aggregate the released ions into a granular state under the action of...

Embodiment 2

[0024]The processing method of a kind of metal tailings slag of the embodiment 2 of the present invention, it is implemented with the metal tailings slag that existing iron ore enterprise produces in the production process as object, and its processing method comprises implementing following steps: The metal tailings slag produced in the beneficiation process is collected and pretreated to remove large particles and impurities, and the precious metals contained in the metal tailings slag are re-extracted through a series of new extraction methods and special equipment. In the process of extracting precious metals, the ore powder collected by air volume and specific gravity separation products is used as clinker for cement production to produce cement.

[0025] The process for extracting precious metals mentioned above is to dry the gold tailings slag, use the instantaneous high temperature generated by electron collision to aggregate the released ions into a granular state unde...

Embodiment 3

[0028] The processing method of a kind of metal tailings slag of the embodiment 3 of the present invention, it is to carry out with the metal tailings slag that existing copper mining enterprise produces in the production process as object, and its processing method comprises the following steps of implementing: The metal tailings slag produced in the process is collected and pretreated to remove large particles and impurities from the tailings slag containing precious metal components in the ionic state. Through a series of new extraction methods and special equipment for precious metals Re-extract the precious metals contained in the metal tailings slag, and at the same time use the ore powder collected by the air volume and specific gravity separation products in the process of extracting precious metals as clinker for cement production to produce cement.

[0029] The process for extracting precious metals mentioned above is to dry the metal tailings slag, use the instantane...

Abstract

The invention discloses a method for handling metal tailing slag, and belongs to the technical field of handling and using the metal tailing slag in the mining industry. According to the technical scheme, the method for handling the metal tailing slag includes the following steps that the metal tailing slag generated in the production process of the metal mining industry is collected and pre-handled, large particles and impurities are removed, and precious metal contained in the metal tailing slag is extracted again through a series of new precious metal extraction process techniques and special-purpose equipment; meanwhile, mineral powder collected by blast capacity proportion separation of products in the precious metal extraction technique process is used as cement production clinker for producing cement. Compared with the prior art, the method has the prominent substantive advantages and remarkable progress that various valuable components in the metal tailing slag are reliably extracted, the utilization rate of mineral resources is increased, the industrial chain is prolonged, the economic benefits of enterprises are increased, and benefits are brought to people and the society.

Description

technical field [0001] The invention relates to the technical field of processing and utilization of metal tailings slag in the mining industry, in particular to the technical field of a treatment method for pollution-free resource utilization of metal tailings slag. Background technique [0002] China is one of the most important gold producing and consuming countries in the world, with gold producing areas spread all over the country, and almost every province has gold reserves. Except for Chongqing, all provinces, municipalities and autonomous regions have proven gold resources. The east is the area where the proven gold resources and reserves are relatively concentrated. Among them, Shandong Province has the highest reserves of rock gold. Gold production is mainly concentrated in Shandong, Henan, Fujian, Liaoning, Hunan, Shaanxi and other places. The country's gold production ranks third in the world after South Africa and the United States. There are more than 80 co...
