FIELD: metallurgy, mining.
SUBSTANCE: method for gold extraction from thrust sulphide ore includes biooxidation with receiving acid pulp and its preparation to sorption leaching of gold by means of neutralisation and by oxygen aeration. At that neutralisation is implemented simultaneously to oxygen aeration at keeping of its content in pulp not less than 10 mg/dm3.
EFFECT: decreasing of elemental sulfur in products of biooxidation before carbonitriding and reduction of materials consumption and duration of preparation for carbonitriding.
