我国砂金矿采探历史悠久,到目前止,砂金生产一直在我国黄金生产中占重要地位,为了实现我国社会主义四个现代化,在近期大力开展砂金探采工作,尤其具有重大的意义。其原因是:砂矿赋存的地质条件比原生矿简单,易于发现,且埋藏浅,勘探设备简易,运输方便,至使评价速度快,采探成本低;工作周期短,选矿回收工艺简单、
Sand gold mining in our country has a long history. Until now, gold production has always occupied an important position in China’s gold production. In order to realize the four modernizations of socialism in our country, it is of great significance in the near future to vigorously carry out exploration and mining of gold and gold. The reason for this is that: the geological conditions of ore deposits are simpler and easier to find than those of the primary ones, and they are shallow buried, the exploration equipment is simple and the transportation is convenient, so that the evaluation speed is quick, the exploration cost is low; the work cycle is short, the beneficiation recovery process is simple,
