一、河南低品位金矿石可浸性试验河南省低品位金矿石资源比较丰富,但矿石类型多,分布广,有些矿山的储量有限,受技术经济条件的限制,难以建立机械化选厂。为充分利用这部分资源,一九八二年以来,我们对这类矿点进行了堆浸提金可行性调查,通过矿石可浸性试验,初步认定有13个矿点适用堆浸提金工艺。这些堆浸矿点通过方案设计已陆续开始堆浸试生产,有
First, the Henan low grade gold ore immersion test Henan Province, low-grade gold ore resources are rich, but many ore types, widely distributed, some reserves of limited reserves, technical and economic conditions, it is difficult to establish a mechanized dressing plant. To make full use of this part of the resources, we have conducted a feasibility study of heap leaching of gold from these deposits since 1982. According to the ore dipping test, 13 ore mines were found to be suitable for heap leaching . These heap leaching mine through the program design has begun heap leaching trial production, there
