Abstract
The orthogonal array design has been used to determine the optimum conditions for gold recovery from
Zarshuran refractory gold sulfide ore (Iran) by direct cyanidation and roasting-cyanidation.
The Taguchi method was used as the experimental design to determine the optimum conditions of dissolution
behavior of gold with cyanidation and roasting-cyanidation from Zarshuran refractory gold ore .
The experimental conditions were studied in the range of 10–12 for pH, 20-40 for time(h), 400-1200 for cyanide
content (g/ton) and 30 -40 for percent solid(%).
Orthogonal array (OA) L9 (34) consisting of four parameters each with three levels, was chosen. From this study for
direct cyanidation the total optimum gold dissolution (30.11%) obtained at pH (10), Time (40 h), Cyanide content
(800g/ton) and Percent solid (30%).
Also for roasting- cyanidation the total optimum gold dissolution (34.96%) obtained at pH (12), Time (40 h), Cyanide
content (1200g/ton) and Percent solid (35%).
