The present invention relates to a process for preparing a low-grade waste zinc oxide (zinc) by dissolving only the zinc coent in the low-grade waste zinc oxide, which is present in a solid state using an organic extractant, into an organic phase and recovering the zinc in the organic phase as an aqueous acid solution, ash. /RTI ;Conventionally, the wet process for recycling spent waste zinc oxide has a very complicated process in which an acid is used to leach out all of the metal coents and to remove the iron impurity, which is the main impurity, and other impurities while taking various steps.;In the present invention, D2A solution of EHPA (trade name) or Versatic aicd 911 (trade name) dissolved in kerosine (trade name) and low-grade waste zinc oxide are mutually contacted to dissolve only zinc oxide, and the zinc dissolved in the organic phase and the undissolved oxide Zinc is recovered and recycled together with an aqueous acid solution.
