The invention belongs to the technical field of solid waste resource utilization, and discloses a method for preparing a high-strength artificial board from nickel smelting slag and biomass waste. The nickel smelting slag and biomass waste particles are added into a hardening and tempering furnace to be smelted, iron produced through smelting is separated, remaining materials are cooled and smashed, and smelting slag is obtained; and the obtained smelting slag is mixed with a solid particle filler and an adhesive according to a ratio, and then material distribution, compression molding and curing are carried out to obtain the high-strength artificial board. By means of the method, the biomass waste and the nickel smelting slag can be effectively recycled, meanwhile, valuable iron elements are obtained through recovery, and three purposes are achieved through one process. Under the condition that natural aggregate is not added into the obtained artificial board, the application performance equivalent to or better than that of an artificial quartz stone board can be achieved. The method has remarkable economic benefits and environmental protection benefits.
本发明属于固废资源化利用技术领域，公开了一种利用镍冶炼炉渣和生物质废料制备高强度人造板材的方法。将镍冶炼炉渣与生物质废料颗粒加入到调质炉内进行熔炼，将熔炼产出的铁分离，剩余物料经冷却粉碎，得到熔炼渣；将所得熔炼渣与固体颗粒填充料和粘合剂按照配比混合，然后经布料、压制成型、固化，得到所述高强度人造板材。本发明方法能够将生物质废料、镍冶炼炉渣均得到有效回收利用，同时回收得到有价铁元素，一举三得。所得人造板材在未添加天然骨料的情况下，可以达到与人造石英石板材相当或更优的应用性能。具有显著的经济效益和环保效益。
