A kind of divalent metal element method for recovering vanadium converter slag

There are one kind of converter method of recovering vanadium slag monovalent metal element, belonging to the field of utilization of resources. The method uses two-stage leaching pattern extracting valuable metals converter vanadium slag: First, the converter vanadium slag crusher with a main component of the mixed raw material of sulfuric acid, agitation leaching to give leachate; secondly, mixing the converter vanadium slag and leachate after leaching to give some leaching pulp are isolated period of leaching the slag with some leaching solution, and then, a period of leaching solution by extraction and back extraction, separation of vanadium, iron and other valuable metals, some leaching residue with a main component into the Sec mixed raw material of sulfuric acid leaching process; Sec leachate obtained into the section of the leaching process, the leaching residue as tailings Sec, mainly composed of silica, cement and other industrial materials may be used, or the like of the silicon carbide material; extract of the present invention has vanadium slag in the converter monovalent metal element, and achieve no residue of the production process, a green vanadium extraction process.
