Method for preparing refractory material from ardealite flotation black carbon-silicon tailings
The invention provides a method for preparing a refractory material from ardealite flotation black carbon-silicon tailings. The method comprises the following steps: washing pretreatment of tailings, preparation of silicon carbide, impurity removal of silicon carbide, and firing-free preparation of the refractory material by using a high-purity silicon carbide raw material and acidolysis residues of a main byproduct aluminum ash in the aluminum industry as raw materials. The refractory material can be prepared by using high-purity silicon carbide, acidolysis residues of aluminum ash and the like as raw materials under the non-burning condition under the condition of a binding agent, and a series of processes of washing pretreatment of black carbon silicon tailings, preparation of silicon carbide raw materials, shaping, acid-base impurity removal of the silicon carbide raw materials and the like are involved in the process. The prepared refractory material has good mechanical strength at medium and low temperatures and high temperatures, the preparation process has the characteristic of low energy consumption, the refractory material is prepared from the coal gasification slag, the aluminum ash acidolysis desiliconization slag and the ardealite flotation black carbon silicon tailings, and synergistic utilization of various solid waste resources is achieved.
