| 摘 要： | 在实验室内进行预富集水中金的各项试验的基础上,选择内蒙古中部地区2个不同自然景观和不同成因类型的金矿床,进行水中金预富集方法各项条件试验和有效性试验。研制出一套快速、简便的野外现场水中金预富集方法技术;发现旱季水中金含量明显高于雨季水中金含量,水化学测量一般宜在旱季进行;采用洗净盐酸型泡塑预富集水中金的方法,在已知金矿开展面积性水化学测量中发现较好的金异常;在疏松厚覆盖区,以往水系沉积物、土壤测量未发现异常的地段,水化学测量有明显的金异常存在,说明该方法在寻找金盲矿方面有其独特的作用。 |
| 关 键 词： | 水中金预富集 洗净盐酸型泡塑 寻找金盲矿 |

| Abstract: | Based on tests of pre-enrichment gold in water, the authors chose two known gold mines with different natural landscape conditions and different genetic types in central Inner Mongolia to test the validity of this technology. A gold pre-enrichment method in water was established with polyurethane foam cleaned by hydrochloric acid. A quick and simple field method for gold pre-enrichment in water was developed. It is found that the gold content of water in the dry season is higher than that in the rainy season. Hydrochemical survey should be usually conducted in the dry season so as to guarantee the consistency of the results. Good gold anomalies were detected in the Donghuofang gold mine, the Laoyanghao gold mine and the peripheral Hejiaoyi belt, which shows that the method is effective. In the area of loosen thick overburden, the performance of the water chemistry survey led to the discovery of gold anomalies which could not be found by stream sediment survey and soil survey in the past, suggesting that the method discussed in the paper is useful in search for blind gold deposits. |
| Keywords: | pre-enrichment of gold in water exploration search for blind gold deposit |
