在有过氧化氢存在的情况下,可用稀酸溶液浸出法从富钴海洋锰结核中快速、有效和有选择性地回收钴、镍和锰,然后可用一般的选择性沉淀法回收这些金属。浸出反应只生成氧作为副产品,对浸出废渣的试验结果表明,根据环境保护局的现行规范,该废渣是无害的。 In the presence of hydrogen peroxide, cobalt, nickel and manganese can be rapidly, efficiently and selectively recovered from cobalt-rich marine manganese nodules using dilute acid leaching methods and these metals can then be recovered by conventional selective precipitation methods. The leaching reaction produces only oxygen as a by-product, and the test results on the leached waste indicate that the waste residue is harmless, according to current regulations of the Environmental Protection Agency.
