The Touzlar gold deposit is located in North-West of Zanjan province,Iran۱:country-region>۱:place>. Extraction of gold from Head sample was done. The head sample contains ۲ ppm Au, ۱۳.۲ ppm Ag, ۵۱۳ ppm Pb, ۸.۲ % Fe۲O۳ and ۶۹.۴۰ % SiO۲. After pretreatment, agitation, bottle roll and column cyanidation tests were done and the gold recovery was about ۹۴%, ۵۹% and ۷۰% 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 ۹۹.۸۷ % and ۹۵.۴ % of gold from solution respectively.
