摘要:
这是一篇矿物加工工程领域的论文。黄铁矿和砷黄铁矿属于常见伴生硫化矿，因二者的晶体结构与表面性质十分相近，所以其浮选分离一直是重要的研究课题。砷硫两种矿物浮选过程中会发生不同程度氧化反应，利用氧化处理技术强化二者的氧化差异，改变矿物本身固有的浮选行为，可以实现砷黄铁矿与黄铁矿的分离。论文从黄铁矿和砷黄铁矿的自身晶体结构与表面性质入手，详细介绍了黄铁矿和砷黄铁矿在氧化浮选分离工艺及机理方面的研究现状及进展，并对研究方向进行了分析展望，希望能够为砷硫矿物的绿色、高效浮选分离提供一定的借鉴。
Abstract:This is an essay in the field of mineral processing engineering. Pyrite and arsenopyrite are common associated sulfides. Because their crystal structures and surface properties are very similar, their flotation separation has been an important research topic. In the flotation process of arsenic and sulfur minerals, the oxidation reaction is easy to occur in different degrees. The oxidation treatment technology is used to strengthen the oxidation difference between the two minerals and to change the inherent flotation behavior of the minerals, the separation of arsenopyrite from pyrite can be realized. Based on the self-crystal structure and surface properties of pyrite and arsenopyrite, the research status and progress of separation technology and mechanism of pyrite and arsenopyrite in oxidative flotation are introduced in detail, the research direction is analyzed and prospected, and it is hoped to provide some reference for the green and efficient flotation separation of arsenic and sulfur minerals.
