황산암모늄에 의한 Copper Sulfide 의 열분해반응

Thermal Decomposition of Copper Sulfide with(NH₄)₂SO₄

김재용, 유영홍

초록

Chalcopyrite로부터 Cu성분의 추출을 위한 새로운 공정을 모색하고자(NH₄)₂SO₄에 의한 CuS의 열분해반응을 조사하였다. 본 반응계에서 CuS는 (NH₄)₂Cu(SO₄)₂와 CuSO₄의 형태로 황산화되어지며 적정반응조건은 반응온도 375℃, 반응시간 40min, CuS에 대한 (NH₄)₂SO₄의 몰비 6.0이었다. 이 조건하에서 99.62%의 Cu가 CuS로부터 추출되었다.

The thermal decomposition of CuS with (NH₄)₂SO₄ was investigated to find a new method for the extraction of Cu component from chalcopyrite. In this reactions, CuS was sulfated to (NH₄)₂SO₂ or CuSO₄ in the N₂ atmosphere and the proper conditions for this sulfation were reaction temperature 375℃, reaction time 40min and mole ratio of (NH₄)₂SO₄ to CuS 6.0. Under these conditions, 99.62% Cu was extracted from CuS.
