Foamed ceramic thermal-insulation material using cyanidation tailings as raw material and preparation method of foamed ceramic thermal-insulation material

The invention belongs to the technical field of metallurgical waste slag recovery, and particularly relates to a foamed ceramic thermal-insulation material using cyanidation tailings as a raw materialand a preparation method of the foamed ceramic thermal-insulation material. The method disclosed by the invention uses the cyanidation tailings as the main raw material, a foam stabilizer, an auxiliary raw material and a foaming agent are additionally mixed, mixing is performed, drying is performed, high-temperature foaming is performed, and therefore the foamed ceramic wall material is prepared.According to the method disclosed by the invention, a large amount of solid waste slag is utilized, and the prepared foamed ceramic material has the characteristics of a light mass, high strength, corrosion resistance, aging resistance and the like, and is a novel thermal-insulation heat-preservation wall material with heat preservation, water resistance, fire resistance, corrosion resistance andaging resistance; and the
