我国天然菱镁矿资源分布之广,储量之多,质量之好,举出罕见。其中辽宁镁矿公司所属矿区更是得天独厚:不仅占全国探明储量的83％而且是生产中、高档出口砂的原料基地。 菱镁石主要用于生产镁砂和轻烧镁。前者用于冶金部门的碱性耐火材料(如镁砖、铬镁砖铝镁砖及冶金镁砂);后者被建材、化工、轻工等部门广为利用。此 China’s natural distribution of magnesite resources, reserves as much, good quality, cited rare. Among them, the mining area owned by Liaoning Magnesium Mine Company is even more advantageous: it not only accounts for 83% of the national proved reserves, but also is the raw material base for producing medium and high-grade export sand. Magnesite is mainly used for the production of magnesia and light burned magnesium. The former is used in the basic refractories (such as magnesia bricks, magnesia bricks, magnesia magnesia bricks, and metallurgical magnesia) in the metallurgical sector; the latter is widely used by construction, chemical and light industries. this
