我国砂金资源丰富,有悠久的淘金历史,但多数砂金矿未作详细的地质工作,黄金储量和品位不清,不能建设大型固定式砂金洗选厂,而适宜实行边采边探或群众采金.目前赋存有砂金资源的地区,群众都有一套传统的淘金技术和经验,但耗用的劳动力多,生产效率低,黄金产量少. China is rich in gold resources and has a long history of gold panning. However, most of the gold deposits have not been subjected to detailed geological work. The reserves and quality of gold reserves are unclear. Large-scale fixed-type gold dust washing plants can not be constructed, Currently, there are a series of traditional gold mining technologies and experiences in the areas where gold resources are still present, but more labor is consumed, productivity is low, and gold production is less.
