초록
납-시금법에서 슬래그로 손실되는 금 손실원인을 규명하고자 하였다. 암석과 정광에 대하여 융제혼합으로 시금법을 수행하고 그 슬래그에 대하여 XRD분석한 결과 방연석, 소금, 납 및 석영이 관찰되었다. 시금법을 수행한 결과, 암석의 슬래그에서 금 손실이 평균 19.86 %인 반면에 정광의 슬래그에서는 평균 12.55 %이였다. 슬래그에서 금이 손실되는 원인은 시금 과정에서 석영이 효과적으로 융해되지 못하였기 때문에 그리고 납이 효과적으로 침전되지 못했기 때문에 일어난 것으로 사료된다. 시금법에서 암석보다 정광에서 금 손실을 줄이는데 붕사가 효과적임을 확인하였다.
Abstract
In order to investigate the reason for gold losses in the lead-fire assay, the salt, galena, lead, and quartz were observed from the results of XRD analysis for the glassy slag from the flux mixture process. In the lead-fire assay, the gold losses were determined to be 20.98% in the slag of the rock, while the gold losses were 12.55% in the slag of the concentrate. The reason for the gold losses in the slag was explained that it may not be effectively decomposed from the quartz and precipitated by the lead in the lead-fire assay process. The borax was suggested to be more effective in reducing gold losses in the concentrate than in the rock.
