Preparation method of high-activity high-purity magnesium oxide
The invention discloses a preparation method of high-activity high-purity magnesium oxide, and belongs to the technical field of mineral resource processing. The preparation method comprises the following steps: (1) cleaning magnesite, namely cleaning low-grade magnesite serving as a raw material; (2) refining magnesite: refining the magnesite cleaned in the step (1), including crushing the magnesite, roasting the crushed magnesite, grinding the magnesite, adding water into the ground magnesite to prepare raw ore pulp, desliming the raw ore pulp, and performing flotation on the deslimed raw ore pulp to obtain concentrate powder; (3) calcining magnesite: calcining the concentrate powder; and (4) performing fine grinding of magnesite: performing fine grinding activation on the calcined concentrate powder. Compared with the prior art, test parameters such as stacking density, active magnesium oxide content, calcium oxide content, hydrochloric acid insoluble substance content, chloride content, ignition loss and the like are remarkably different, and the magnesium oxide is high-quality high-activity high-purity magnesium oxide.
本发明公开了一种高活性高纯氧化镁的制备方法，属于矿产资源加工技术领域。所述制备方法，包括以下步骤：(1)菱镁矿的清洗：以低品位菱镁矿为原料，清洗；(2)菱镁矿的精制：将步骤(1)清洗后的菱镁矿进行精制，包括菱镁矿破碎、破碎后菱镁矿焙烧、菱镁矿研磨、研磨后的菱镁矿加水制成原矿浆、原矿浆脱泥及脱泥后的原矿浆浮选，得到精矿粉；(3)菱镁矿的煅烧：将精矿粉进行煅烧；(4)菱镁矿的细磨：将煅烧后精矿粉末进行细磨活化。与现有技术相比，堆积密度、活性氧化镁含量、氧化钙含量、盐酸不溶物含量、氯化物含量及灼烧失量等试验参数均体现了显著性差异，为优质的高活性高纯氧化镁。
