摘 要: 提出一种富集和提取镓的新方法———吸附沉淀法.在一定的试验条件下,使单宁和镓生成有色的单宁 镓络合物,利用活性炭吸附有色络合物,把单宁 镓络合物吸附到活性炭上,过滤分离,灼烧滤渣,得到了含镓量较高的灰分,实现了镓的分离、富集和提取,回收率达到99%以上. A new technique was first researched on gallium solvent extraction and enrichment. On some conditions, Tannin and gallium come into being colored chelate Tannin-gallium compound, which can be adsorbed by active carbon . After filtering and incinerating the sediment, Authors got the ashes which contain high content of gallium. The recovery was over 99% .
