Abstract

암모늄염의 열분해 반응을 이용하여 chalcopyrite로부터 Cu성분의 추출을 위한 새로운 공정을 시도하였다. 이 공정은 NH₄Cl에 의한 chalcopyrite의 염소화 반응과 그 결과 얻어진 인공 CuS의 (NH₄)₂SO₄에 의한 황산화 반응으로 이루어져 있다. 이 공정을 통하여 Cu성분의 99.55%rk chalcopyrite로부터 추출되어 진다.

A new process for the extraction of Cu component from the chalcopyrite was attempted by thermal decomposition method of ammonium salts such as ammonium chloride or ammonium sulfate. This process consists of chlorination of chalcopyrite with NH₄Cl and sulfation of Synthetic CuS which was obtained from the chlorination of chalcopyrite with (NH₄)₂SO₄. Through this process, overall 99.55% Cu component was extracted from the chalcopyrite.
