镓是具有重要用途的稀散金属。攀枝花地区共生铁矿含镓,但直接从矿石或攀钢高炉铁水中提取镓,其镓的品位太低。攀钢雾化提钒的钒渣中含镓约0.015％～0.02％,已高于世界生产镓主要原料铝钒土的含镓量。 我们进行的研究包括两部分:一是试通过攀钢铁水的氯化处理提取镓;二是试通过钒渣的氯化焙烧、或通过浸钒渣的氯化焙烧或熔融还原或浸取,来提取镓。以上工艺均将镓作为生产钒的副产品,试图开辟出生产镓的新途径并降低镓的生产成本。
Gallium is an important use of scattered metals. Panzhihua co-production of iron ore containing gallium, but directly from the ore or Panzhihua Iron and Steel blast furnace hot metal gallium extraction, the gallium grade is too low. Pangang vanadium atomized vanadium slag containing gallium content of about 0.015% ~ 0.02%, higher than the world production of gallium main raw material of aluminum bauxite gallium content. Our research includes two parts: one is to try to extract gallium through the chlorination of hot metal in Panzhihua Iron and Steel; the other is to pass the chlorination roasting of vanadium slag or the chlorination roasting or melting reduction or leaching of vanadium leaching residue to Gallium extraction. The above processes all use gallium as a by-product of the production of vanadium in an attempt to open up new ways of producing gallium and reduce the production cost of gallium.
