In order to study the phase transformation of pyrite and to determine the maximum Fe leaching factors, pyrite samples were an electric furnace and microwave oven and then ammonia leaching was carried out. The rim structure of hematite was observed in the sample exposed in an electric furnace, wherea...

황철석이 고령토, 엽납석, 활석에서 함께 산출되면 품위가 저하되는 이유는 무엇인가? | 황철석은 금광석광물(gold-bearing ore mineral)에서 흔히 산출되는 황화광물이다. 황철석이 고령토, 엽납석, 활석에서 함께 산출되면 이들 산업광물을 고온-가공-처리하는 과정에서 Fe가 산화-착색되어 품위가 저하된다(Ubaldini et al., 1996). | |
황철석이란? | 황철석은 금광석광물(gold-bearing ore mineral)에서 흔히 산출되는 황화광물이다. 황철석이 고령토, 엽납석, 활석에서 함께 산출되면 이들 산업광물을 고온-가공-처리하는 과정에서 Fe가 산화-착색되어 품위가 저하된다(Ubaldini et al. | |
비-가시성 금의 분해하는 방법 중 마이크로웨이브로 가열 방법의 원리는 무엇인가? | 비-가시성 황철석이 마이크로웨이브 에너지에 의해 가열되면 자류철석(pyrrhotite)과 적철석(hematite)으로 변환 된다(La Brooy, 1994). 이때 황철석의 S가 SO2로 제거되기 때문에 다공성 재질로 변환되어 공극률이 증가된다. 그러므로 액상의 금 용매제가 이들 공극 사이를 용이하게 침투되므로 금용출이 향상된다(Prasad et al., 1991; Amankwah et al. |
