对加温及增强渗透提高浸堆金浸率的探讨

ON THE IMPROVING AU RATIO LEACHED BY HEATING AND RAISING PERMEABILITY

采用堆浸法提金工艺处理低品位金矿的技术在世界发达国家或地区已经日益趋于成熟，我国在研究应用低品位金矿堆浸技术方面也已经取得了较大成就，但对低温地区的浸堆加温及含粉矿、粘土矿物较高的金矿石解决渗透性的堆浸技术方面，我国矿业界仍需要加快研究。

The technique,low grade gold ore treated by the heap leaching,is becoming mature day by day in developed countries and regions.The researches and applications for the heap leaching technique of low grade gold ore in China have achieved remarkable progress.The author consides that the heap leaching technique in respect to heap leaching and heating in low temperature region and to permeability of gold ore with highter powdery are and clay mineral in China shold be quickly researched so as to develop Chinese gold industry and to protect gold ore resources.
