据《加拿大采矿与冶金通报》报道,美国麦吉尔大学对提取难选矿石和精矿中贵精属的各种湿冶方法作了综评。第一种化学氧化方法已由美国卡林厂和坎宁厂用于处理含碳矿石。往矿浆中送入气态Cl_2。由于Cl_2消耗大(>200kg/t),对此工作做了改进,并获得成功。研制了“喷来”氯化流程,其主要特点在于设备配置。近几年还研制了两种流程—NITROX流程,ARSENO流程和其改进型REDOX流程。这些流程都属化学氧化法处理难选物料。第一种流程是使用硝酸作载氧体。当氧化矿浆中的硫化物时,
According to the “Canadian Mining and Metallurgical Bulletin” reported that the United States McGill University extraction of hard-to-concentrate ore and refined precious Metallurgy all kinds of wet-smelting methods were reviewed. The first chemical oxidation process has been used by the Carrington and Canning plants in the United States for the treatment of carbonaceous ores. Into the slurry into the gaseous Cl_2. Due to the high consumption of Cl 2 (> 200 kg / t), this work has been improved and succeeded. Developed a “spray to” chlorination process, the main feature is the device configuration. In recent years, two processes have also been developed: the NITROX process, the ARSENO process and its improved REDOX process. These processes are chemical oxidation of refractory materials. The first process uses nitric acid as the oxygen carrier. When oxidizing sulfide in the slurry,
