国内采矿业仍完全处于价格低落的严重影响之下,从而促使成本低廉的溶浸采矿工艺继续发展。今年3月在美国新奥尔良市召开的115届美国矿冶工程学会年会以“溶浸采矿工艺与环境问题”为主题的学术研讨会上,发表了几篇与堆浸和原地浸出法回收 The domestic mining industry is still completely under the severe impact of low prices, prompting the continued development of cost-effective leaching mining processes. In March this year in New Orleans, the United States held the 115th annual meeting of the American Society of Mining and Metallurgical Engineering “leaching mining technology and environmental issues” as the theme of the academic seminar, published several heap leaching and in situ leaching recovery
