“…The direct dewatering of such finely divided leach suspension by conventional sedimentation is difficult and physical-chemical characteristics of the slurries must be changed in order to achieve higher settling velocities. In practice, this needed modification of the leach residues involves the addition of destabilizing agents, i. e. and organic polymer, to flocculate the particle and to produce settleable aggregates [30,31].…”

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.
