摘要
卡林型金矿中的碳质物的"劫金"作用是导致其难处理的原因之一。由于不同的碳质物结构及组成不同,其对卡林型金矿的处理有着不同的影响。本文研究了三个不同地区的卡林型金矿中碳质物的组成。结果表明,不同样品的碳质物组成及元素碳形貌都有明显的差异。因此,金矿中的碳质物组成与金矿形成时的地质时期及地质作用有密切关系,不同地区,不同时期形成的金矿其碳质物的组成有很大差异。
One of reasons that leads to the refractory Carlin-gold is the pre-robbing effect due to different structure and composition of carbonaceous material, it has a different impact on the Carlin-type gold processing. Composition of carbonaceous materials of Carlin-gold ores in three different areas was studied. The results showed that the carbo- naceous materials were significantly different in composition and morphology. So it was closely related to the geolog- ical period and geological processes for carbonaceous materials. Its composition were very different in different re- gions and different periods.
