选择性萃取被认为选出高选择性的萃取剂实现多萃钒少萃铁或不萃铁，并可在萃

Selective extraction of selected high selectivity is considered 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.

Selective extraction is considered to select highly selective extractors to achieve multi-extract less or no iron, and can add a washing process between extraction and anti-extraction, thus achieving a complete separation of radon and iron.

Selective extraction is considered to select highly selective extractant to extract more vanadium and less iron or no iron, and a washing process can be added between extraction and stripping to realize complete separation of vanadium and iron.<br>
