Abstract

1. Способ извлечения благородных металлов из упорного сульфидного сырья, включающий сверхтонкое измельчение, предварительную обработку пульпы при повышенной температуре и сорбционное цианирование, отличающийся тем, что предварительную обработку проводят в две стадии: первую стадию осуществляют в присутствии кислорода, вторую - в присутствии кислорода и извести.2. Способ по п. 1, отличающийся тем, что концентрат измельчают до крупности 95,0% класса минус 10 мкм и менее.3. Способ по п. 1, отличающийся тем, что окислительную обработку кислородом ведут до pH 2-3, известковую - до pH 10,5-11,0.4. Способ по п. 1, отличающийся тем, что предварительную обработку проводят таким образом, чтобы степень окисления сульфидов составляла 35-55%.1. The method of extraction of precious metals from refractory sulfide raw materials, including ultrafine grinding, pulp pretreatment at elevated temperature and sorption cyanidation, characterized in that the pretreatment is carried out in two stages: the first stage is carried out in the presence of oxygen, the second in the presence of oxygen and lime .2. The method according to p. 1, characterized in that the concentrate is crushed to a particle size of 95.0% of the class minus 10 microns or less. The method according to p. 1, characterized in that the oxidative treatment with oxygen is carried out to a pH of 2-3, lime - to a pH of 10.5-11.0.4. The method according to p. 1, characterized in that the preliminary treatment is carried out so that the oxidation state of sulfides is 35-55%.
