玉龙铜矿氧化带中含铜钴的锰水合氧化物胶体的研究

运用综合手段对此前未见报导的西藏玉龙铜矿氧化带矿石中锰的水合氧化物进行了工艺矿物学研究．结果表明它是同时富含铜、钴、铅的胶体，该氧化带矿石中约８％的铜和４０％的钴均赋存于此．对其浸溶行为的研究证明，提取冶金过程中设法破坏该锰胶体是获得较好铜、钴回收率的必要条件．

STUDY ON COLLOID OF MANGANESE HYDRATED Cu AND Co IN OXIDATION ZONE AT YULONG COPPER MINE IN TIBET

The process mineralogical investigation to the manganese hydrated oxide unreported before at YulongCopper Mine has been carried out by means of the comprehensive methods. The results show that it is acolloid phase containing abundant Cu, Co, Pb. Approximately 8% copper and 40% cobalt in the oxidationore are distributed in this phase. The study on its leaching behavior proves that it is requisite to break themanganese hydrated oxide colloid for getting more sufficient recovery of copper and cobalt.
