堆浸设计几个问题的探讨

An approach to some problems in heap leaching design

Starting from heap leaching design, a few technological and ecoon-mical problems concerning geology, mining, mineral processing and leaching pad are discussed in this paper. Comparisions in the technology and economy of heap lea-ching between the operations at home and abroad are made, showing that heap leaching technology has been successfully applied in China, although there are still incom-plete aspects as compared with the world level,and it is needed to make further researches on the new technology.The author points out that in order to utilize low-grade gold ores steadily, special measures and policies should be adopted and the exploration of geological resources be speeded up, for making more benefits from gold extraction by heap leaching.
