堆浸提金技术及其在塘家冲金矿的应用

Technology for heap leaching of gold and its application in pond's blunt gold

本文由两部分构成。第一部分首先介绍了堆浸提金技术及其机理,接着介绍了铁矿物、铜矿物、锌矿物、砷锑矿物、汞铅矿、含碳矿物对堆浸效果的影响,矿石结构和粒度、氰化物及浓度、氧的浓度、PH值、喷淋强度、筑堆高度等技术参数对堆浸过程的影响。第二部分介绍了塘家冲金矿的矿体、矿石、矿床工业指标及资源量,矿石的工艺矿物学特征及选矿性能,讲述了塘家冲金矿从工业试验、直接堆浸、制粒堆浸试验、直到制粒堆浸工艺确定的整个过程,并提出了今后制粒堆浸作业中应注意的几个问题。

This paper consists of two parts. The first part first introduced the technique and its mechanism for heap leaching of gold, and then introduces the iron ore, copper, zinc, arsenic, antimony, lead, mercury carbon minerals on the effects of the heap leaching ore structure and particle size, concentration of cyanide and, oxygen concentration, PH value, the strength of spray, built pile height, etc. The influence of technical parameters on the heap leaching process. The second part introduces the pond's blunt gold ore bodies, ore, ore deposit industrial index and the resource, process mineralogy characteristics and ore dressing performance, tells the story of pond house rushed from the industrial test, direct heap leaching, gold granulation heap leaching test, until sure the whole process of granulation heap leaching process, and system in the future was put forward several problems that should be paid attention to in the grain heap leaching operation.
