This study used microwave-nitric acid leaching with the aim of removing penalty elements such as As and Bi. Moreover, enhanced gold content from the gold concentrate sample. The leaching conditions were changed: leaching time, nitric acid concentrations and solid-liquid ratio; In order to improve th...

금의 정제에서 페널티 원소인 비소와 비스무스가 얼마나 포함되어 있으면 패널티를 부과하는가? | 수십 혹은 수백 톤의 정광을 먼 거리의 제련소까지 운반하다 보니 운반 경비가 막대하게 소요된다. 또한, 금 정광이나 구리 정광 등에 비소와 비스무스가 각각 2,000, 500ppm 이상으로 포함되어 있으면 페널티(penalty)가 부과되고 있다(Tongamp et al., 2009; Celep et al. | |
arsenian pyrite란 무엇인가? | 현재, 우리나라에서는 비소를 함유하는 황철석, 즉 arsenian pyrite로 구성된 금 정광을 소규모 광산에서 제련소로 납품하고 있다. 수십 혹은 수백 톤의 정광을 먼 거리의 제련소까지 운반하다 보니 운반 경비가 막대하게 소요된다. | |
전자현미경을 사용해도 금을 관측하기 어려운 이유는 무엇인가? | , 2008). 즉, 금이 황철석과 황비철석에 극 미립크기로 존재하기 때문에 현미경이나 심지어 전자현미경에서 조차 금을 관찰하기 어렵다. 그리고 금을 다량 함유한 황철석에는 항상 비소가 포함되어 있다. |
