The invention provides a method for producing a moonlight metal tile by using red mud and the moonlight metal tile, and belongs to the technical field of comprehensive utilization of solid waste residues. The red mud is used as a main raw material, and iron oxide in the red mud is reduced to generate elemental iron by adopting a reduction calcination process; the elemental iron is carbonized to form silver gray iron carbide which is not easily oxidized again by using excessive reducing agent carbon, so that the product is endowed with silver gray, the product can reflect silver light under moonlight and then becomes a high-quality material for various pseudo-classic buildings, and the effects of harmlessly treating the red mud slag and increasing economic benefits are achieved; the problem that existing red mud cannot be utilized harmlessly with high added value all the time is solved, and the problem that in the prior art, when an antique building material-moonlight metal tile is produced, the requirement for the content of aluminum and iron in raw materials is harsh is solved.
本发明提供了一种利用赤泥生产月光金属瓦的方法及月光金属瓦，属于固废渣的综合利用技术领域，本发明以赤泥为主要原料，采用还原煅烧工艺将赤泥中的铁氧化物被还原产生单质铁，并利用过量的还原剂碳使得单质铁被碳化形成不易被再度氧化的银灰色碳化铁，进而赋予了产品银灰色，使其能够在月光下反射银光，进而成为各大仿古建筑的优质材料，实现了赤泥渣无害处理，并增加经济效益的效果，解决了现有赤泥一直无法高附加值无害化利用的困境，并克服了现有技术中生产仿古建材‑月光金属瓦时对原料中铝铁含量要求苛刻的难题。
