【摘要】 矿物学研究结果表明,该含铀多金属矿的矿物成分和化学成分都很复杂,锌矿物主要为异极矿,其次为锌锰矿等氧化物;铅矿物主要为铅锰矿,其次为黑铅矿等氧化物;锰矿物主要为锌锰矿、铅锰矿和软锰矿等氧化物;铀矿物主要为铀酸铅等表生矿物;铁矿物主要为褐铁矿和赤铁矿,微量的磁铁矿和黄铁矿。对该矿石进行了铀的浸出工艺试验。研究表明,硫酸搅拌浸出时,铀的浸出率可达90%;碱法搅拌浸出时,铀浸出率仅为10%左右;酸法柱浸结果为,-5mm矿样的铀渣计浸出率可达91.5%,酸耗为20.8%;-10mm矿样的铀渣计浸出率可达88.4%,酸耗为19.5%。因此该矿可采用酸法堆浸工艺浸出其中的铀。更多还原

【Abstract】 The mineral components and chemical components of the metal mine containing uranium and other kinds of metallic elements are complicated with mineralogy research.The main zinc mineral is Calamine.The main lead mineral is cesarolite.The main manganese minerals are cesarolite and heterolite.The main iron minerals are limonite and hematite. And the main uranium mineral is PbUCv The leaching technology tests of uranium of the ore are taken.Research shows that the leaching rate of uranium up to 90%with acidic agitation leaching,while it only about 10%with alkaline agitation leaching.And the leaching rate of uranium up to 91.5%,with acidic column leaching to the -5mm ore sample. While the leaching rate up to 88.4%with the -10mm ore sample.Therefore,uranium can be used with acid heap leaching technology in the mine.更多还原
