可通过选矿预处理、选择性浸出和选择性萃取多种手段来解决“高铁低钒而导致

Can solve problems "iron caused by low vanadium vanadium and iron can not be effectively separated" by the pre-dressing, selective extraction, and selective leaching various means. I.e. the mineral preprocessing portion ferromagnetic iron in the slag is removed and recovered by conventional weak magnetic separation. Namely the use of selective extraction of vanadium, iron leaching behavior differences partially separated using "prepreg iron, vanadium leaching section Ⅱ Ⅰ segments" approach, in the leaching stage to achieve the vanadium and iron. Selective extraction of high selectivity i.e. preferably multi-extraction of vanadium extraction agent extraction of iron little or no extraction of iron, and can increase a washing step between the extraction and stripping, in order to achieve complete separation of vanadium and iron.

The problem of "effective separation between radon and iron due to low high-speed rail" can be solved by pre-treatment, selective leaching and selective extraction. Pre-treatment is the use of the traditional weak magnetic selection method to remove and recycle some of the strong magnetic iron in the steel slag. Selective leaching is the use of the difference between radon and iron leaching behavior using the "I segment pre-immersion iron, II leaching" method, in the leaching stage to achieve partial separation of radon and iron. Selective extraction is the selection of highly selective extractors to achieve multi-extract less or no iron, and can add a washing process between extraction and anti-extraction, so as to achieve a complete separation of radon and iron. ...

The problem of "high iron and low vanadium lead to the failure of effective separation of vanadium and iron" can be solved by means of mineral pretreatment, selective leaching and selective extraction. Beneficiation pretreatment is to use the traditional weak magnetic separation method to remove and recover part of the strong magnetic iron in the steel slag. Selective leaching is to use the difference of leaching behavior of vanadium and iron to achieve partial separation of vanadium and iron in the leaching stage. Selective extraction is to select highly selective extractant to extract more vanadium and less iron or no iron, and to add a washing process between extraction and stripping, so as to realize complete separation of vanadium and iron.<br>
