耐火矾土在矾土和氧化铝工业中有着广泛的用途。矾土最基本的用途是在生产铝的冶金部门,占矾土总消耗量的85％。其余的矾土消耗可分为特种氧化铝和“其它”两大类。特种铝中矾土用于生产氢氧化铝、煅烧氧化铝和活性氧化铝,占矾土总消耗量的10％。“其它”类占矾土总耗量的5％,指直接用于像耐火材料、水泥和腐蚀剂工业等开采的矾土。就市场规模和价值而言,耐火矾土在这种非冶金市场最终用途中占有重要的地位。
Bauxite has a wide range of uses in the alumina and alumina industries. The most basic use of bauxite is in the metallurgical sector that produces aluminum, which accounts for 85% of the total bauxite consumption. The remaining alumina consumption can be divided into special alumina and “other” two categories. Special aluminum medium alumina is used to produce aluminum hydroxide, calcined alumina and activated alumina, accounting for 10% of the total consumption of bauxite. The “other” category accounts for 5% of the total bauxite consumption and refers directly to the use of bauxite for the mining of refractory materials, cement and corrosive industries. In terms of market size and value, refractory bauxite plays an important role in the end-use of this non-metallurgical market.
