当今约85%的金属镓是从氧化铝生产过程中回收的。我厂的产镓量约占世界产镓总量的四分之一,而目前回收的镓量仅为可回收量的30%左右。提镓潜力发挥不出来的主要障碍,是回收镓排出的大量碳酸化母液和铝钙渣(每回收一公斤镓排出:碳酸化母液85米~3、铝酸钙残渣7.5吨),长期未能得到有效利用。
About 85% of today’s metallic gallium is recovered from the alumina production process. The output of Gallium in our plant accounts for about a quarter of the world’s gallium production, but the current recovery of Gallium is only about 30% of the recoverable amount. The main obstacle to mentioning the potential of gallium is to recover a large amount of carbonated mother liquor and aluminum calcium slag discharged from gallium (one kilogram of recovered gallium per gallon: 85 to 3 carbonated mother liquor and 7.5 tons of calcium aluminate residue) for a long period of time Get effective use.
