    摘要: A metal hydroxide complex has a formula Me(OH)4*Anull*nH2O or MeO2*Anull*nH2O. Preferred complexes are formed in an alkaline medium, and particularly especially preferred anions include cyanide and cyanide gold complexes. Contemplated complexes are formed on a metal hydroxide (e.g., hydrated zirconium, hafnium, and titanium hydroxide), which may be disposed in a porous container. Consequently, contemplated compounds may be used in methods of reducing the concentration of an anion in an alkaline medium.

    摘要: A rapid, energy efficient, low cost, nonhazardous method for the selective removal of mercury from mercury-containing metal cyanide solutions, particularly the cyanide solutions resulting from the cyanidation of gold ore and the like, wherein a reactive sulfide is admixed with the solution for a time sufficient to form an insoluble mercuric sulfide precipitate. The mercuric sulfide precipitate is then separated from the metal cyanide solution by filtration or other conventional means.
