    摘要: A metal stripping system and an operation process therefor which includes the following elements and steps. A main part of this system is a crystallization apparatus for metal stripping comprising a mixing zone of organic solvent and fluoride series stripping solution, a settling zone for organic solvent, a settling zone for stripping solution, a separation zone for fluorinated metal complex crystal and a stripping solution cooling zone. In the operation of the system wherein the organic solvent containing extracted metal ions is contacted with the fluoride series stripping solution to deposit the fluorinated metal complex crystal and then the crystal is recovered as metal or metal oxide, the stripping solution is circularly used by supplying NH.sub.4 HF.sub.2 solution to the cooling zone, supplying the stripping solution discharged from the apparatus and absorbed with a decomposition gas of the crystal to the mixing zone, and supplying a filtrate after the crystal separation to the settling zone for stripping solution.
