本文针对贵州省的黄金资源情况,较全面、具体、通俗地阐述了微细粒金矿提金的实用技术.鉴于微细粒金矿提金的关键问题是使矿石中的金转入溶液中,本文详述了不同化学溶金试剂溶解金的原理、物理化学条件、影响因素和优缺点.由于氰化法提金工艺技术成熟、简单,成本较低,本文对影响氰化溶金的因素和实际对策以及氰化提金的传统工艺(槽浸法:渗滤法和搅拌法)的装置、生产条件、技术指标等作了具体的实用性的介绍;同时对现代提金的新技术、新工艺——堆浸法和炭浆法作了较详细介绍;对于难选难浸矿石也指出了开发利用的途径;针对氰化法提金中的环境保护问题,介绍了处理氰化废水的一种实用方法.
This article aims at the gold resources in Guizhou Province, and presents a more comprehensive, specific and general description of the practical technology of gold extraction from fine-grained gold deposits.According to the key problem of gold extraction from fine-grained gold deposits, the gold in ore is transferred into solution The principles, physical and chemical conditions, influential factors and advantages and disadvantages of gold dissolved by different chemical gold-dissolving agents are described in detail.As the technology of gold extraction by cyanidation is mature, simple and low cost, Countermeasures and the traditional process of cyanide gold extraction (tank dipping method: percolation method and stirring method) of the device, production conditions, technical indicators made a specific practical introduction; at the same time on the modern gold technology, new technology - heap leaching method and carbon slurry method were described in more detail; hard to pick difficult ore also pointed out the development and utilization of ways; for cyanidation of gold in the environmental protection issues, introduced a cyanide wastewater treatment Practical methods.
