FIELD: mining industry. SUBSTANCE: invention mainly concerns gold sulfide and carbonate ores. Ore treatment is performed in two steps. In the first step, sulfides are oxidized or carbonates are dissolved using mixture of oxygen-containing gas and sulfur dioxide. In the second step, ore is leached with chlorine aqueous solution. Return solution from the first step is purified from salts either via alkali precipitation or via cation-exchange treatment, the both procedures being accompanied by Fe(II) oxidation. Productive chloride solution is processed by known methods of cementation, sorption, or electrolysis. Once process is completed, formation solution is deactivated by sulfur dioxide and neutralized with alkali. Method allows involving deposits early regarded as unprofitable, especially those containing finely dispersed gold and located in permafrost zone among them. EFFECT: increased gold recovery degree; reduced chlorine consumption; and improved environmental safety due to low salt concentration in produced formation solution (of order of 1 g/l). 7 cl
