摘要:

含锑金矿是常见的难处理金矿,金被包裹在辉锑矿等硫化物矿中,由于锑的存在,直接对其进行氰化浸出,金的提取率较低,通过预处理法先将锑矿物脱除,是提高金浸出率的关键。通过介绍浮选法,火法中的焙烧和熔炼,湿法中的酸浸、碱浸、加压浸出和生物浸出等工艺及其原理,对比了各工艺的优缺点,分析了各工艺产业化的现状。基于研究结果,认为含锑金矿的研究应朝着更环保、更高效、更安全的方向发展,因此,湿法预处理成为研究的重点,新型工艺手段的应用和新型药剂的开发既可以确保高效安全,又可以保证环保经济。

Abstract:

Antimony-bearing gold ore is a common refractory gold ore.Gold is often wrapped in antimonite and other sulfide ores,due to the presence of antimony,the extraction rate of gold is often low when leaching by the traditional cyanide method.Removal of antimony minerals through pretreatment method is of great importance to enhance the leaching efficiency of gold.This paper introduces the recent development on the pretreatment methods,such as flotation,roasting,acid or alkaline leaching,biological leaching and pressure leaching.The advantages and disadvantages of different processes were compared and the status quo of industrialization of each process was analyzed.Based on the research results, it is believed that the research of antimony-bearing gold mines should be developed in a more environmentally friendly, more efficient, and safer direction.Therefore,hydrometallurgy has become the focus of research.The application of new process methods and the development of new agents can not only ensure high efficiency and safety,but also ensure environmental protection and economy.

Key words: antimony-bearing gold ore, pretreatment, antimony removal, flotation, pyrometallurgy, hydro-metallurgy
