汤丹氧化铜矿是我国一座大型贫铜矿床。由于难选，至今还未很好开发利用，加工方案一直有争论。尽管自５０年代以来，先后有原苏联、英、美、原西德、瑞典、日本等国公司的研究部门做了一些工作，但未能取得进展。国内也有一些研究部门，特别是东川科技工作为之奋斗几十年，取得一定进展。本次试验采用深度活化浮选和新药剂ＡＭ—８９所获得的经济效果比其它方案都好，可以认为是目前全浮选最佳加工方案。
Tangdan copper oxide oxide is a large copper-poor deposit in China. Due to difficult choice, so far not yet well developed and processing options have been controversial. Although there have been some work done by the research departments of the former Soviet Union, Britain, the United States, former West Germany, Sweden, Japan and other countries since the 1950s, no progress has been made. There are also some domestic research departments, especially Dongchuan science and technology work for decades, made some progress. The test results using the depth of activated flotation and the new agent AM-89 obtained economic effect than other programs are good, can be considered the best flotation processing options.
