摘要
在金矿中,金、硫、砷相互嵌合,如果提取工艺不当,很难提高金矿的开采率,而浮选分离技术能够提高金的富集率,但它也受到相关因素的限制。对于含砷金矿来说,它具有一定的特点:成分复杂、砷含量过高、砷硫分离困难等,均对金矿中金的提取造成了很大的困难。金是一种稳定的物质,很难与其他物质发生反应,这也是金矿提取困难的根本原因。本文主要对金的概述、金矿石选矿的现状进行分析,进一步研究金硫砷浮选分离技术。
Gold, sulfur and arsenic are embedded in gold deposits, and if the extraction process is inappropriate, it is difficult to raise the mining rate of gold deposits, while flotation separation technology can increase the enrichment rate of gold, but it is also limited by the relevant factors. For the arsenic-bearing gold deposits, it has certain characteristics： complex composition, high arsenic content, the separation of arsenic and sulfur, etc., all of gold extraction caused great difficulties. Gold is a stable substance, it is difficult to react with other substances, which is the root cause of the difficulty in extracting gold. In this paper, the summary of gold, the status quo of ore dressing analysis, further study of gold sulfur arsenic flotation separation technology.
