초록

2014년까지, 페루에서는 천4백만톤의 연(금속기준)과 4천백만톤의 아연(금속기준)이 생산된 것으로 집계되었다. 페루에서는 연과 아연 관련하여 대표적인 두 개의 금속광화대가 알려져 있다. 첫 번째 금속광화대는 백악기 전기-효신세 화산성 괴상 황화물 Cu-Zn-Au 광화대이며, 두 번째 금속광화대는 중신세 천열수, 스카른, 교대 및 다금속 맥상 광화대이다. 2017년까지 4개의 신규 채광 프로젝트가 시작되고 이어서 3개의 추가 프로젝트가 준비된다면, 34만톤의 연과 150만톤의 아연이 추가적으로 생산되는 것이 가능할 것으로 사료된다. 페루의 연-아연 금속광화대에서는, 아연의 부존량 및 품위는 각각 9~6000 백만톤, 0.1~14% Zn이며, 연의 부존량 및 품위는 각각 5~2800 백만톤, 0.04~5.3% Zn인 것으로 사료된다.

Until 2014, 14 million tonnes of Pb (metal based) and 41 million tonnes of Zn (metal based) were produced in Peru. Representative two Pb-Zn metallogenic belts were known in Peru. They are lower Cretaceous-Paleocene VMS Cu-Zn-Au metallogenic belt and Miocene epithermal, skarn, replacement & polymetallic vein metallogenic belt. If four new mining projects were launched and additional three mining projects were prepared until 2017, it seems possible to produce 0.34 million tonnes of Pb and 1.5 million tonnes of Zn additionally. In Pb-Zn metallogenic belt in Peru, potential Zn amounts range from 9 to 6000 million tonnes with 0.1 to 14% Zn and potential Pb amounts range from 5 to 2800 million tonnes with 0.04 to 5.3% Pb.
