Method for preparing ceramic sintered water permeable brick from tungsten tailings
The invention discloses a method for preparing a ceramic sintered water permeable brick from tungsten tailings. The tungsten tailings are used as aggregate, a plastic mineral raw material is mixed with water, and/or a binder is used as a batch, and the water permeable brick is prepared by ball milling, mixing, pressure forming and sintering. The method comprises the following steps: (1) preparing aggregate, including crushing, screening and grain grading of tungsten tailings; (2) preparing the batch, namely ball-milling and mixing the plastic mineral raw material, the binder and water; (3) mixing the aggregate and the batch, including stirring and aging the mixture; (4) material distribution and molding of the mixture, including two times of material distribution and one-time compression molding of a backing material and a surface material; and (5) sintering the water permeable brick, including low-temperature moisture drying, high-temperature sintering and crystal phase control of a cooling area. The ceramic sintered water permeable brick has good mechanical strength and water retention and permeability, and is excellent in wear resistance and corrosion resistance. According to the method, comprehensive treatment and high-value utilization of the tungsten tailings are achieved, and remarkable economic and environment-friendly benefits are achieved.
本发明公开了一种钨尾砂制备陶瓷烧结透水砖的方法，以钨尾砂为骨料，可塑性矿物原料和水混合、和/或粘结剂为配合料，经球磨、混合、压力成型和烧结制备透水砖，步骤如下：(1)骨料的制备，包括钨尾砂的破碎、筛分和颗粒级配；(2)配合料的制备，包括可塑性矿物原料、粘结剂和水的球磨混合；(3)骨料与配合料的混合，包括混合料的搅拌和陈腐；(4)混合料的布料与成型，包括底料和面料的两次布料及一次压制成型；(5)透水砖的烧结，包括低温的水分烘干、高温的烧结和冷却区的晶相控制。陶瓷烧结透水砖具有较好的机械强度和保水透水性，以及耐磨、耐腐蚀性优越。本发明实现了钨尾砂的综合处置及高值化利用，具有显著的经济和环保效益。
