The invention discloses a method for preparing lightweight foamed ceramic with nickel slag and pulverized biomass. The method includes the following steps: mixing, by mass, 27-72 parts of nickel slag, 28-73 parts of aluminium silicon waste slag, 15-30 parts of pulverized biomass and 1-6 parts of foaming agent prior to uniform blending and forming to obtain green bodies; putting the green bodies into a high temperature furnace for sintering, and cooling to room temperature to obtain the lightweight foamed ceramic. 本发明公开了种利用镍渣和生物质粉制备轻质发泡陶瓷的方法，包括以下步骤：将镍渣、硅铝废渣、生物质粉和发泡剂混合，按质量份数计，配比为镍渣27～72份、硅铝废渣28～73份，外加生物质粉15～30份和发泡剂1～6份，混合均匀，成型，得到坯体；将坯体在高温炉内进行烧结，冷却至室温，得到轻质发泡陶瓷。
