Application and Progress of Pressure Hydrometallurgy of Cu-Ni Sulfide Ores Containing Platinum Group Metals

Recently, the pressure hydrometallurgy applied for treatment of non ferrous metal sulfide ores has developed rapidly. The technology has manifested irrefutable advantages in aspect of environment protection and extraction of metals. On basis of leaching process behaviors of platinum-group metals(PGMs) the lately progress in pressure hydrometallurgy of Cu Ni sulfide ores containing PGMs were presented. The typical processes including pressure ammonia leaching, pressure acid leaching, pressure alkaline leaching and pressure cyanide leaching were reviewed, including their ore characters, technological parameters and industrial practice. The behaviors of PGMs in pressure hydrometallurgy processes were also discussed.
