【摘要】 采用盐酸-硝酸铵体系对钼铋废催化剂中有价元素钼、镍、钴、铋、浸出。钼抑制于固相,直接用纯碱浸之,制成纯度较高的钼盐。镍、钴、铋水解成相应的氢氧化物,具有设备简单、易操作、成本低的特点。更多还原

【Abstract】 Molybdnem,nickle,cobalt and bismuth is leached from molybdenum and bismuth spent catalysts through the system of hydrochloric acid-ammonium nitrate.Molybdenum is restrained in solid phase,and leached directly with alkali to produce molybdate with high purity.Nickle,cobalt and bismuth are turned into corresponding hydrated oxide by hydrolysis.更多还原
