Method for preparing low-cost inorganic artificial stone from tungsten tailings
The invention discloses a method for preparing low-cost inorganic artificial stone from tungsten tailings. The method comprises the following steps: carrying out clarification treatment on tungsten tailing slurry, and crushing caked tungsten tailings into fine sand by using a crusher; all the raw materials are put into a stirring pot according to a certain proportion to be stirred, the water reducing agent and water are mixed and then added in batches, and the stirred raw materials are poured into a mold; shaping is conducted after compression molding, and then the shaped artificial stone plate is subjected to steam curing; and taking out the steamed inorganic artificial stone plate, and cutting and testing the inorganic artificial stone plate according to a bending strength and compression strength test method in the national standard. According to the invention, the cost is reduced by using the tungsten tailings to replace the aggregate, the tungsten tailings are not screened, the cost is saved in process, the proportion of the tungsten tailings is increased, the proportion of the cement and the aggregate is greatly reduced, and the formula cost is saved due to the fact that no flexibilizer such as emulsion is added in the scheme.
本发明公开了一种钨尾矿制备低成本无机人造石的方法。该方法包括以下步骤：将钨尾矿浆料澄清处理，使用粉碎机将结块的钨尾矿粉碎为细沙状；将所有原料按照一定比例放入搅拌锅中搅拌，减水剂与水混合后分批次加入，将搅拌好的原料倒入模具中；压制成型后定形，接着将定形后的人造石板蒸养；取出蒸养好得无机人造石板，按照国标中的弯曲强度和压缩强度试验方法，对无机人造石板材进行切割和测试。本发明通过使用钨尾矿替代骨料降低成本，并未对钨尾矿进行筛分处理，在工艺上节约成本，通过将钨尾矿的占比提高，使水泥及骨料的占比大大减少，并且本方案未添加乳液等增韧剂，从而在配方上节约成本。
