Abstract

The invention provides an electrolytic manganese residue ceramic, a preparation method thereof and a ceramic tile, and relates to the technical field of ceramics. The electrolytic manganese residue ceramic is mainly prepared from the following raw materials in parts by mass: 40-55 parts of electrolytic manganese residues, 10-15 parts of calcined limestone, 15-30 parts of ceramic waste residues and10-20 parts of fly ash. The electrolytic manganese residues, the fly ash and the ceramic waste residues are used as raw materials of the electrolytic manganese slag ceramic, so that cyclic utilization of the electrolytic manganese residues, the fly ash and the ceramic waste residues can be realized, the comprehensive utilization rate of the raw materials is improved, residue of the waste residuesin the environment is reduced, environmental pressure is effectively relieved, and the method has great significance for environmental protection.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to electrolytic manganese slag ceramics, a preparation method thereof and ceramic tiles. Background technique [0002] Electrolytic manganese slag is the filtered acid slag produced after electrolysis of metal manganese, and is a key pollutant in the electrolytic manganese industry. The treatment of electrolytic manganese slag faces two problems: (1) the stock of electrolytic manganese slag is large, and (2) the utilization rate is very low. In addition, the emission of ceramic waste makes it a huge pressure on the environment. Fly ash is the fine ash collected from the flue gas after coal combustion in the process of power production, and it is the main solid waste discharged from coal-fired power plants. Fly ash will pollute the atmosphere; if it is discharged into the water system, it will cause river silting, and it will also cause harm to humans and organisms. In order to a...
