Utilization method of graphite tailings
The invention provides a utilization method of graphite tailings, which adopts graphite tailings, soda ash, calcium carbonate and dolomite as main raw materials and a small amount of boric acid or borax as an additive, carrying out high-temperature calcination melting in a high-temperature furnace, cooling water to form water-quenched particles, carrying out ball milling by a ball mill, and screening to obtain a low-melting-point powder assistant; the low-temperature co-fired ceramic additive can be used as a good additive of low-temperature co-fired ceramic. According to the powder additive prepared by the method, the calcining temperature of the co-fired ceramic is effectively reduced, the energy consumption is reduced, meanwhile, the graphite tailings are effectively utilized as processing raw materials, the powder additive is more environment-friendly, and efficient utilization of solid waste resources is realized.
本发明提供一种石墨尾矿的利用方法，以石墨尾矿、纯碱、碳酸钙、白云石为主要原料，以少量硼酸或硼砂作为添加剂，在高温炉中进行高温煅烧熔制，然后过冷却水后形成水淬颗粒，经球磨机球磨后筛分得到低熔点粉体助剂，可作为一种低温共烧陶瓷的良好助剂。本发明制备得到的粉体助剂有效地降低共烧陶瓷的煅烧温度，降低能耗，同时有效地利用了石墨尾矿作为加工原料，更环保，实现固废资源的高效利用。
