本文研究了金矿物平衡在制订难选金矿石的详细冶金试验方案和工艺条件优化选择方面的重要意义。对32种金矿石和含金矿石已经制定和试验了能获得完全和定量矿物平衡的工艺程序。这种程序基于用标准氰化法测定”可见金”含量並用光学显微术和电子探针分析技术鉴定“可见金”矿物。导致矿石难于直接氰化处理的“不可见”金(即胶体金和固溶体金)则直接用定量离子探针分析方法(SIMS)测定。所有载金矿物都进行直接鉴定,因而能获得精确可靠的结果。文中列举了五种金矿石的试验研究工作例子。本文的目的在于对通过识别鉴定金的存在形式来改善工艺设计和优化工艺过程的金工艺矿物学研究方法进行分类归纳。
This paper studies the significance of gold mineral balance in the detailed metallurgical test program and optimization of process conditions in the development of refractory gold ore. For 32 gold and gold-bearing ores, process procedures have been developed and tested to achieve complete and quantitative mineral balance. This procedure is based on the determination of the “visible gold” content by standard cyanidation methods and the identification of “visible gold” minerals using optical microscopy and electron probe analysis techniques. “Invisible” gold (ie, colloidal gold and solid solution gold) that causes the ore to be difficult to directly cyanide is directly measured by quantitative ion probe analysis (SIMS). All gold-bearing minerals are directly identified and accurate and reliable results are obtained. The article lists five kinds of gold ore experimental research work. The purpose of this paper is to classify the research methods of gold process mineralogy by improving the process design and optimizing the process by identifying the existence of the identification gold.
