据有关方面了解,我国目前已能堆浸十几万吨规模的矿堆,浸出率最高可达80～90％。新疆、浙江,安徽等地的堆浸矿山效益明显。 1988年前,我国金矿堆浸最大规模仅为万吨级,一般为千吨级,效益上不去,污染问题也因规模小而难以治理。1987年,前全国金矿地质工作领导小组办公室组团考察美、 According to the parties concerned, China is now able to heap leaching hundreds of thousands of tons of ore mines, leaching rate of up to 80 to 90%. Heap leaching mines in Xinjiang, Zhejiang and Anhui have obvious benefits. Before 1988, the largest scale of heap leaching of gold in our country was only 10,000-tonne class, generally it was one-thousand-tonne class, and the efficiency was not improved. The problem of pollution was also difficult to be solved because of its small scale. In 1987, the former national geological work leading group office of the delegation inspected the United States,
