Abstract

본 발명은 중석(重石 : 텅스텐)을 함유한 고철(Hard Scrap)에 Na염을 이용하여 중석 및 유가금속을 회수하는 것에 관한 것으로, 중석(重石)을 함유한 고철(Hard Scrap)을 예열시키는 제1공정과, 상기 고철에 Na염(NaNO3및 NaOH)을 가하는 용해시키는 제2공정과 이어서 NaNO2를 가하여 상기 반응을 촉진시키는 제3공정과, 상기 용융액을 냉각시킨후 물을 가해 텅스텐을 분해시키는 제4공정과, 상기 분해후 텅스텐 화합물 함유용액과 기타 유가금속 함유잔사로 분리시키는 공정으로 이루어짐을 특징으로 하는 함 중석(重石) 고철(Hard Scrap)의 처리방법에 관한 기술임.The present invention relates to the recovery of bitumen and valuable metals using Na salt in a hard scrap containing tungsten (heavy stone: tungsten), the agent for preheating the hard scrap (heavy scrap) containing scrap A first step of dissolving Na salt (NaNO 3 and NaOH) to the scrap metal, followed by a third step of promoting the reaction by adding NaNO 2 , and cooling the melt and adding water to decompose tungsten And a fourth step of the step and a step of separating the tungsten compound-containing solution and other valuable metal-containing residues after the decomposition.
