Method for preparing magnesia-calcium sand from high-silicon magnesite tailings
The invention discloses a method for preparing magnesia-calcium sand from high-silicon magnesite tailings, which comprises the following steps of: a, crushing the high-silicon magnesite tailings, adding water to form high-silicon magnesite tailings pulp, adding the high-silicon magnesite tailings pulp into a flotation machine, adding a flotation agent into the flotation machine, and starting the flotation machine to remove iron and silicon from the high-silicon magnesite tailings; and b, drying the high-silicon magnesite tailings, and calcining the dried high-silicon magnesite tailings in a combustion furnace. The method has the advantages that the process is simple, the labor intensity is reduced, the equipment requirement is low, special synthesis equipment and a treatment technology are not needed, and the synthesized magnesia-calcium sand has the advantages of high purity, wide application range, good sintering performance, excellent hydration resistance and no influence on the high-temperature use performance of the magnesia-calcium sand; the magnesium-calcium sand can be produced and prepared through one-step calcination, fuel can be remarkably saved, the cost is effectively reduced, waste tailings are effectively utilized, and pollution is reduced.
本发明公开了一种高硅菱镁矿尾矿制备镁钙砂的方法，包括以下步骤：步骤a：将高硅菱镁矿尾矿粉碎后加水，形成高硅菱镁矿尾矿浆，将高硅菱镁矿尾矿浆加入浮选机中，向浮选机中加入浮选剂，启动浮选机对高硅菱镁矿尾矿进行除铁脱硅；步骤b：对高硅菱镁矿尾矿进行烘干，烘干后将高硅菱镁矿尾矿置于燃烧炉中煅烧。本发明实现了具备工艺简单，降低劳动强度，设备要求低，无需特殊合成设备与处理技术，所合成的镁钙砂具有纯度高、应用范围广、烧结性能好、抗水化性优良，且不影响其高温使用性能的优点，利用尾矿代替白云石，经一步煅烧就可生产制备镁钙砂，可以显著的节省燃料，有效降低成本、有效利用废弃尾矿，减少污染。
