Gold recovery optimization of a refractory concentrate by ultrafine grinding - a laboratory study

Effect of lead nitrate. Some works have shown that lead nitrate addition increases gold leaching kinetics and decreases cyanide consumption by reducing the sulfide dissolution ([Desch]ênes et al . . 2000 ; Deschênes et al . , 2003 ; Deschênes . 2005 ) . In order to study the effect of this salt in c...

Description
Summary:Effect of lead nitrate. Some works have shown that lead nitrate addition increases gold leaching kinetics and decreases cyanide consumption by reducing the sulfide dissolution ([Desch]ênes et al . . 2000 ; Deschênes et al . , 2003 ; Deschênes . 2005 ) . In order to study the effect of this salt in cyanidation. two lead nitrate additions were studied (100 and 300 g Pb(NO,)2/t.
