Abstract
1. Способ извлечения золота из концентратов, включающий окисление и выщелачивание концентратов щелочными растворами ферроцианидов натрия или калия при нагревании, отличающийся тем, что окисление и выщелачивание концентратов осуществляют в одну стадию обработкой его при температуре 80-90°С растворами ферроцианидов, содержащими в качестве окислителей хлорную известь или персульфат щелочного металла или аммония, при этом pH растворов выщелачивания выдерживают в пределах 12,5-13,5. ! 2. Способ по п.1, отличающийся тем, что растворы выщелачивания содержат 5-20 г/л ферроцианидов натрия или калия. ! 3. Способ по п.1, отличающийся тем, что растворы выщелачивания содержат хлорную известь или персульфат натрия или калия или аммония в количестве 10-20 г/л раствора. ! 4. Способ по п.1 или 2, отличающийся тем, что при использовании в качестве окислителя персульфата натрия или калия или аммония растворы выщелачивания содержат гидроксид натрия или калия в количестве 5-10 г/л раствора. ! 5. Способ по п.1, отличающийся тем, что массовое отношение концентрата к раствору выщелачивания составляет 1:3. ! 6. Способ по п.1, отличающийся тем, что выщелачивание сырья ведут в течение 5 ч. 1. The method of extracting gold from concentrates, including the oxidation and leaching of concentrates with alkaline solutions of sodium or potassium ferrocyanides, when heated, characterized in that the oxidation and leaching of concentrates is carried out in one step by treating it at a temperature of 80-90 ° C with solutions of ferrocyanides containing as oxidizing agents bleach or alkali metal or ammonium persulfate, while the pH of the leach solutions is kept in the range of 12.5-13.5. ! 2. The method according to claim 1, characterized in that the leach solutions contain 5-20 g / l of sodium or potassium ferrocyanides. ! 3. The method according to claim 1, characterized in that the leach solutions contain bleach or sodium or potassium or ammonium persulfate in an amount of 10-20 g / l of solution. ! 4. The method according to claim 1 or 2, characterized in that when using sodium or potassium or ammonium persulfate as an oxidizing agent, the leach solutions contain sodium or potassium hydroxide in an amount of 5-10 g / l of solution. ! 5. The method according to claim 1, characterized in that the mass ratio of the concentrate to the leach solution is 1: 3. ! 6. The method according to claim 1, characterized in that the leaching of raw materials is carried out for 5 hours
