Abstract: 

The Sharafabad gold deposit is located in east Azerbaijan province north-west of Iran. Extraction of gold from main vein was done. The head sample contains 5.7 ppm Au, 4.2 ppm Ag, 0.55 % Pb, 9.68 % Fe2O3 and 74.24 % SiO2. After pretreatment, agitation and bottle roll cyanidation and a combination of tests the gold recovery was about 96.76%, 65.5% and 95.09% respectively. After optimization of cyanidation for the gold extraction carbon active and zinc foil tests were investigated on pregnant liquid. Active carbon and zinc foil recovered 99.79 % and 79.17 % of gold from solution respectively.
