Procedure for elution of precious metals adsorbed on Activated Carbon by direct or with preimpregnacion elution elution

摘要

The present Invention relates to a procedure to gold and / or silver to elute the adsorbed on Activated Carbon by elution or by Direct elution with preimpregnacion,Understanding the ELU - tion directly put the carbon in contact with an eluent containing a cyanide solution and / or a base and optionally an organic Solvent under conditions such that the CarboNot to me - We are being partially absorbed Materials,Obtaining a product eluate containing Gold and / or silver containing understanding and elution with carbon preimpregnacion put in contact with a solution that contains preimpregnacionAnd a cianuto and / or a base and optionally an organic Solvent, so as to pro - duce carbon prepreg which is suitable to be eluted and a solution of preimpregnacion Aug - tadaCarbon prepreg and put in contact with an aqueous or organic eluent in conditions such that the impregnated carbon stripped to me - We partially adsorbed materials.Ob - taking a product containing eluate containing Gold and / or Silver.
