Silver tailing sand high-strength ceramsite and preparation method thereof

Abstract

The invention provides silver tailing sand high-strength ceramsite. The silver tailing sand high-strength ceramsite is prepared from the following raw materials by mass percent: 45 to 55 percent of silver tailing sand, 4 to 8 percent of magnesium residue, 5 to 8 percent of fine steel residue powder, 20 to 30 percent of diatomite, 5 to 7 percent of glued stone, and 6 to 12 percent of rice husks. According to the silver tailing sand high-strength ceramsite, the silver tailing sand and the diatomite are used as main raw materials, the magnesium residue, red mud and rice husks are used as auxiliary materials, and the raw materials are the industrial and agricultural waste, so that the production cost of the ceramsite can be greatly reduced, the environmental pollution problem caused by the stacking of the silver tailing sand can also be solved, and the resource utilization rate of the silver tailing sand and the land utilization rate can be improved; and in addition, the ceramsite preparedfrom the silver tailing sand has the characteristics of high strength, low water absorption rate and the like, can meet the quality inspection requirement of the standard light aggregates and test method thereof GB / T 17431.1- 1998 for the finished product ceramsite, and can be widely applied to the industries such as road transportation, construction materials, garden landscaping and the like.

Description

technical field [0001] The invention relates to the field of solid waste utilization and environmental protection, in particular to a silver tailing sand high-strength ceramsite and a preparation method thereof. Background technique [0002] Silver tailings are the discarded slag of silver mines after the selection of silver by mineral processing equipment. The discarded silver tailings not only occupy a large amount of land, pollute the nearby water sources and air, but also seriously affect the personal safety and development of the surrounding areas. It is an industry Common problems that need to be solved urgently. At present, domestic methods for processing and comprehensive utilization of silver tailings are very limited, and the depth of research is relatively shallow. The only methods for utilizing silver tailings are as follows: (1) Patent CN107522405A uses silver tailings to produce foam glass, but there is no detailed introduction to the specific ingredients and ...

Problems solved by technology

At present, domestic methods for processing and comprehensive utilization of silver tailings are very limited, and the depth of research is relatively shallow. The only methods for utilizing silver tailings are as follows: (1) Patent CN107522405A uses silver tailings to produce foam glass, but there is no detailed introduction to the specific ingredients and process of producing foam glass from silver tailings

(2) Patent CN103373839B uses silver tailings to make concrete blocks, but the amount of silver tailings used is very low, and chemicals are used, which increases production costs

At present, the production technology of using silver tailing sand to prepare ceramsite is very scarce. How to use silver tailing sand as the main raw material, design a reasonable composition formula, and prepare high-strength ceramsite with excellent performance is a technical problem to be solved by the patent of the present invention
