Abstract

Cyanidation has been used worldwide to recover gold from primary ore or concentrate. The use of cyanide is however becoming an emerging issue because of the toxic residue and wastewater made from the process. The cyanide-containing wastewater should be treated properly, obeying the environmental standard and regulations. In the present article, the domestic and international uses, regulations, and treatment technologies of cyanide in gold mining were investigated as a feasibility study to develop a cyanide treatment process as well as the cyanidation process. A biological cyanide treatment process to develop a zeroemission gold recovery and wastewater treatment process was also briefly introduced.

전세계적으로 시안화법은 일차 광물 혹은 정광으로부터 금을 회수하기 위해 널리 사용되어 왔다. 그러나 이 공정에서 발생하는 다량의 유독한 잔사 및 시안 함유 폐액은 주변 환경 및 생태계에 심각한 문제를 야기할 수 있어 그 사용에 대해 문제가 제기되어 왔으므로 시안화법 이용 시 반드시 시안 함유 폐액의 적절한 처리가 필요하다. 본 연구에서는 금광으로부터 금을 회수하기 위한 습식제련공정인 시안화법과 연계하여 시안 처리 공정을 설계하기 위한 기초연구로서 금 제련에 사용되는 시안화합물의 사용, 규제 및 처리 기술의 국내외 현황을 분석하였다. 또한 무배출 금 회수 및 처리 공정을 설계하기 위한 생물학적 공정에 대하여 소개하였다.
