Method for preparing light-burned magnesia from magnesite flotation tailings
The invention relates to the technical field of mineral processing, in particular to a method for preparing light-burned magnesia from magnesite flotation tailings, which comprises the following steps: S1, collecting the magnesite flotation tailings, and classifying and screening; s2, high-purity magnesium-containing tailings are separated from the screened magnesite flotation tailings; s3, the separated magnesium-containing tailings are ground to the nanoscale particle size; s4, harmful impurities in the tailings are removed through an ion exchange technology; s5, carrying out drying treatment by using a microwave drying technology; s6, carrying out surface modification treatment on the dried tailings by utilizing a plasma technology; s7, carrying out high-temperature roasting on the modified tailings to prepare light-burned magnesia; and S8, then carrying out particle-level separation to obtain products with different particle size specifications. According to the method, the resource recovery rate and the product quality are remarkably improved, meanwhile, the energy consumption and the environmental influence are reduced, and the method has wide application prospects and remarkable economic benefits.
本发明涉及矿物加工技术领域，具体涉及一种菱镁矿浮选尾矿制备轻烧镁砂的方法，包括以下步骤：S1：收集菱镁矿浮选尾矿并进行分级筛选；S2：从筛选后的菱镁矿浮选尾矿中分离出高纯度的含镁尾矿；S3：将分离出的含镁尾矿研磨至纳米级粒径；S4：通过离子交换技术去除尾矿中的有害杂质；S5：使用微波干燥技术，进行干燥处理；S6：利用等离子体技术对干燥后的尾矿进行表面改性处理；S7：对改性后的尾矿进行高温焙烧，制得轻烧镁砂；S8：然后进行微粒级分离，以得到不同粒径规格的产品。本发明，不仅显著提高了资源回收率和产品质量，同时降低了能耗和环境影响，具有广阔的应用前景和显著的经济效益。
