CN103572046A - Method for dissolving niobium-tantalum

The invention relates to a method for dissolving niobium-tantalum ore with KOH for extracting niobium and tantalum. The method comprises two key steps of: dissolving the niobium-tantalum ore with a KOH solution (35-50 wt%), and dissolving out niobium and tantalum from the ore with a low-density HF solution (5-25 wt%) by leaching. The niobium-tantalum ore generates insoluble solid-phase ...
