The invention relates to a square brick preparation method and a product thereof, wherein industrial waste is used as a raw material, the billet body comprises, by weight, 50-75% of iron ore and 25-50% of feldspar tailings, material preparing, dry ball milling, sieving, granulating, pressing molding and microwave firing are performed to obtain the product, the sintering temperature is 1000-1050 DEG C, the firing time is 2-3 h, and the thermal insulation time is 10-15 min. According to the present invention, by completely using the industrial waste as the raw material, the prepared square brickhas a water absorption rate of less than 3.5% and a compressive strength of 75-125 MPa, such that the insufficient ceramic raw material is saved, and the national energy conservation and emission reduction policy is met so as to achieve wide application prospects. 本发明涉及一种广场砖的制备方法及其制得的产品,采用工业废料为原料,其坯体配方的重量百分比组成为：铁矿砂50～75%、长石矿尾砂25～50%，经配料、干法球磨、过筛、造粒、压制成型、微波烧成获得制品，其中烧结温度为：1000～1050℃、成时间为：2~3h、保温时间为：10～15min，本发明完全采用工业废料为原料，制
