Description

technical field

[0001] The invention belongs to the technical field of building materials, in particular to a cement clinker mixed with tailing slag and ash and a preparation method thereof. Background technique

[0002] Tailings slag and ash are by-products of the metal industry. The main chemical components of tailings slag are silica, iron oxide, alumina, calcium oxide, etc., and some also contain non-ferrous metals or rare metals; they are generally discharged from the concentrator in slurry form. , the particle size is usually 0.001 to 1 mm, and it is easy to dust and pollute the atmospheric environment after drying. Ash and slag refer to the final product formed after the minerals in coal are burned in the furnace under the high temperature caused by certain physical and chemical changes. Problems such as corrosion and heating surface wear affect the normal operation of the boiler, and the ash and slag must be removed effectively and timely.

[0003] At present, the ...
