| 摘 要： | 高含泥氧化矿石浸堆因渗透性差而影响堆浸的正常进行.渗透试验表明,高含泥氧化矿石矿堆的渗透性与矿石粒级组成密切相关,采取矿石堆浸粒级划分:-1 mm为泥质物,+5 mm为块状矿,5～1 mm之间为粉状矿.在此基础上,提出了分粒级筑堆技术,即先对矿石进行分级,然后按粒级分区筑堆,对不同粒级浸堆采用不同的布液强度.该项技术应... |

| Abstract: | The poor permeability of copper oxide ore with high-clay affects the effects of heap leaching.The infiltration experiments show that the permeability of ore is closely related to its particle size composition,which indicates that the classification boundary of argillaceous matter should be 0-1mm,the boundary of massive ore should be larger than 5 mm,while the intermediate is powder ore.On this basis,the classification heap-constructing technology is proposed,which is to construct different heaps according to the classification of ore particle sizes and to distribute different solution intensity in different heaps.The technology has been applied in a copper mine in Yunnan province and has eliminated the surface fluid runoff and accumulation phenomena.Qualified leaching solution can be produced and the leaching rate of copper reaches 63.98 %.The new technology saves the leaching-extraction-electrowinning production line. |
| Keywords: | high-clay copper oxide ore heap leaching classification heap-constructing leaching rate |
