| titleOfInvention | Extraction of nickel and vanadium from black polymetallic shale based on microbial fluorination leaching |
| abstract | The invention provides a process for extracting nickel and vanadium in black polymetallic shale based on microbial fluorination leaching. The process mainly includes: using the exclusive leaching bacteria of black polymetallic shale to carry out microbial fluorination leaching of black polymetallic shale to obtain a leaching solution; extracting V(IV) ions from the leaching solution based on extraction technology, and extracting the vanadium-containing shale obtained The noble liquid can directly prepare vanadium electrolyte; remove molybdenum ions in the vanadium raffinate by adjusting the pH of the vanadium raffinate obtained by extraction to 5.0 to 5.5 to obtain a purified solution; use ion exchange resin to extract Ni ( II) ions to obtain a nickel-containing noble liquid that can directly prepare nickel sulfate. This process not only has a short process, but also is suitable for ferrous polymetallic shale with various nickel and vanadium contents. It can also effectively leaching nickel, vanadium and other valuable metals in ferrous polymetallic shale, which provides an easy-to-handle vanadium extraction process for shale. At the same time, the process also has the advantages of high resource utilization rate, small impact on the environment and good economy, and has broad application prospects. |
