对于难处理硫化矿石预氧化处理,迄今已有多种工艺发展成熟,进入应用阶段,如生物氧化和加压氧化工艺。奥尔滨工艺则是难处理硫化矿预氧化的一种崭新技术。奥尔滨工艺诞生于1993年,并且已获得国际专利。
For refractory sulfide ore pre-oxidation treatment, so far there have been a variety of mature technology to enter the application stage, such as bio-oxidation and pressurized oxidation process. Orbin process is difficult to deal with sulfide ore pre-oxidation of a new technology. Orbin craft was born in 1993, and has obtained international patents.
