摘　　要：针对高海拔地区硫化锌精矿高效清洁利用的需要以及国际上没有高海拔地区硫化矿氧压浸出技术研究及工业化生产先例的现状,首创了独特的两段逆流控铁氧压浸出工艺、矿浆降温降压缓释能技术及系统以及创新设计了高压釜的结构形式,形成系统技术,解决了制约高海拔地区硫化锌精矿氧压浸出的系列技术难题,并实现了产业化应用。Aimed at the need of efficient and clean use of zinc sulfide concentrate in high altitude area and the status of no international precedent of research and industrial production of oxygen pressure leaching technology for sulfide concentrate in high altitude area,this paper pioneered the unique two-stage counter-current iron-controlling oxygen pressure leaching process,and the pulp cooling,depressurization,and slow-release technology and system,as well as innovatively designed the structure of autoclave.It formed the system technology,solved a series of technical problems restricting the oxygen pressure leaching for zinc sulfide concentrate in high altitude area,and realized the industrial application.
