四川某金矿提高堆浸技术指标的生产实践

Practice of a gold mine in Sichuan Province in promoting the techincal indexes of heap leaching

某金矿通过对堆浸工艺的技术改造,采取建设正规化永久性堆场、降低入堆矿石粒度、革新使 用新型炭吸附工艺等措施,使堆浸技术指标得到了显著提高。堆浸回收率由原来的75.84％提高到81.34％。

Through the technical renovation in heap leaching such as establishing the regular and permanent heap yard, reducing the ore grain size and utiliaing the now type carbon adsorption technology, the technical indexes of heap leaching are significantly promoted and the heap leaching recovery is upgraded from 75.84%to 81.34% in this gold mine.
