“…The economic feasibility of the HPAL route for the extraction of nickel and cobalt values from silicate ores is highly dependent upon the behavior of aqueous aluminum. This is primarily due to its precipitation as hydronium alunite ((H 3 O)Al 3 (SO 4 ) 2 (OH) 6 ), which is one of the major scale-forming compounds found in autoclaves used for pressure leaching [28]. Less recognized is the potential for formation of MgSO 4 ·X H 2 O and silica scale.…”

Abstract:A wide spectrum of hydrometallurgical processes offers many promising approaches for industrial application in order to improve the environmental impact of conventional metals productions, or for replacing pyrometallurgical processes whose gas emissions and a high content of formed metals (As, Cr, Pb) (gold, zinc, molybdenium, titanium, germanium) from ore deposits and secondary materials. High pressure leaching in combination with other metallurgical operations (cementation, precipitation, solvent extraction, and electrowinning) provides an adequate technology to reintroduce lost metals into the industrial cycle, thereby saving resources and energy, while keeping the environment cleaner. It seems that pressure hydrometallurgy might be a very important key to better and nonpolluting processes in production of metals.
