Problems solved by technology

Due to the existing technology, the metals and non-metals contained in the fine-grained muddy part have not been reasonably and effectively developed and utilized, resulting in a large amount of metals and non-metals becoming solid hazardous waste, which has caused serious environmental protection and safety. Threats, to some extent also increase the difficulty of environmental governance

Embodiment Construction

[0019] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0020] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

Abstract

The invention discloses a metal and nonmetal medium-fine fraction argillization treatment process which comprises the following steps: grinding raw materials and carrying out flotation treatment to generate a part of mineral aggregate which cannot be directly recycled, and adding sulfide into the mineral aggregate to obtain a mixture A and a mixture B; screening and filtering the mixture A to obtain a sulfide product and a fine-fraction mud product A; adding an oxide into the mixture B to obtain a mixture C and tailings; screening and filtering the mixture C to obtain an oxide product and a fine-fraction mud product B; mixing and screening the fine-fraction mud product A and the fine-fraction mud product B to obtain recyclable fine-fraction mud products and tailings; and mixing the tailings to obtain total tailings, and discharging the total tailings outwards. The treatment process is mainly used for treating fine-fraction argillization parts in various metal and non-metal production raw materials, segmented treatment is adopted, the recycling rate of valuable metal and non-metal is increased, and meanwhile the heavy metal content of tailings is reduced.

Description

technical field [0001] The invention relates to the technical field of metal and non-metal fine-grained mud, in particular to a metal and non-metal fine-grain mud treatment process. Background technique [0002] my country is the largest producer of metals and non-metals. In most of the metal and non-metal production raw materials in my country, the fine-grained muddy part accounts for a large proportion, accounting for about 40%. However, the potential economic value of metals and non-metals contained in the 40% fine-grained muddy part cannot be estimated. For a long time, the development and comprehensive recycling of fine-grained muddy resources in metal and non-metal production raw materials has been highly concerned by people from all walks of life in the industry, and a lot of effort has been devoted to it. [0003] Since the 1980s, various non-ferrous metal and non-metal industries and related professional colleges and universities at home and abroad have successive...
