长江中下游,沿长江断裂带,在石炭系,二迭系和三迭系地层中,广泛发育着中——酸性浅成侵入——次火山岩有关的铜铁硫化矿床,大多数矿床含钴较高,达综合利用价值,为工物用钴的重要资源。其中钴的富集具有明显的规律。矿床地质特征和含钴情况列于表1。根据上述矿床中矿石的主要金属矿物(黄铁矿,磁铁矿,磁黄铁矿和黄铜矿组合比 In the middle and lower reaches of the Yangtze River, along the fault zone of the Yangtze River, medium-acidic acid-rich intrusive-subvolcanic copper-iron sulfide deposits are widely developed in the Carboniferous, Permian and Triassic strata. Most deposits contain more cobalt High, up to the value of comprehensive utilization of cobalt for industrial use is an important resource. Among them, cobalt enrichment has obvious regularity. The geological characteristics of the deposit and the cobalt content are listed in Table 1. According to the above ore deposits in the main metal minerals (pyrite, magnetite, pyrrhotite and chalcopyrite combination ratio
