RECOVERING METHOD OF URANIUM AND VANADIUM FROM A BLACK SLATE

摘要

PURPOSE: A recovering method of uranium and vanadium from a black slate is provided to effectively leach uranium and vanadium included in a black slate and to economically collect the uranium and vanadium from a solution left behind after the leaching.;CONSTITUTION: A recovering method of uranium and vanadium from a black slate comprises the steps of: (S10) pulverizing and fracturing a black slate, (S20) firstly leaching the pulverized and fractured black slate, (S30) separating the first leached material into solid and liquid, (S40) extracting uranium from the liquid separated from the first solid-liquid separation and (S50) extracting vanadium after oxidizing the remaining vanadium of the solvent extraction of uranium.;COPYRIGHT KIPO 2013;[Reference numerals] (S10) Processing a mineral after pulverization and fracturing; (S20) Firstly leaching the processed mineral; (S30) Firstly separating the firstly leached material into solid and liquid; (S40) Solvent-extracting uranium from the liquid separated from the first solid-liquid separation; (S50) Solvent-extracting vanadium after oxidizing remaining raffinate
