Problems solved by technology

At present, the treatment of rare earth tailings is mainly carried out by stacking or landfilling, which not only occupies a large area, causes serious pollution to the environment and has great potential safety hazards, but also causes a lot of waste of resources and damages the local ecological environment. And the development of enterprises and regional economy has a serious impact

Abstract

The invention discloses a permeable ceramic brick manufactured from rare earth tailings. The permeable ceramic brick is manufactured by wrapping binding coarse rare-earth tailing particles with a wrapping material. The permeable ceramic brick is manufactured from the following raw materials: 65-80 wt% of coarse rare-earth tailings, 3-10wt% of fine rare-earth tailings, 2-6wt% of clay and 10-20wt% of flux, wherein the mixture of the fine rare-earth tailings, the clay and the flux functions as the wrapping material. In addition, the invention further discloses a manufacturing method of the permeable ceramic brick. The waste rear-earth resources are recycled, and the permeable ceramic brick with good water permeability and water retention and high strength is obtained, thus the purpose of protecting environment can be achieved, and the development of industry, regional economic and urbanization can be promoted.

Description

technical field [0001] The invention relates to the technical field of building ceramic materials, in particular to a ceramic permeable brick prepared from rare earth tailings and a manufacturing method thereof. Background technique [0002] With the continuous advancement and development of my country's new urbanization construction, urban public places need to be covered with a large number of pavement building materials. Traditional pavement construction materials are impermeable and airtight cement bricks. This hardened ground has no water retention function and cannot absorb rainwater when it rains, causing a large amount of rainwater to flow into rivers, causing floods and causing water shortages on the urban surface, resulting in The "urban heat island effect" is becoming more and more serious. The permeable brick is a new type of pavement building material with both water permeability and water retention functions. Its promotion and use will undoubtedly help solve t...
