Claims (4)

1. Способ выделения золота из золотосодержащего сырья, заключающийся в том, что исходный материал смешивают с реагентом, в состав которого входят щелочи (NaOH, KOH), смесь нагревают до состояния расплава и выдерживают в нагретом состоянии, после чего расплав обрабатывают водой, фильтруют с отделением осадка и извлекают золото, отличающийся тем, что в качестве щелочи используют также LiOH, в состав реагента входят также селитры (NaNo3, NaNO2, KNO3, KNO2) в массовом соотношении щелочь:селитра от 1:1 до 6:1, массовое соотношение реагента с исходным материалом берут не менее 2,5:1, а температуру нагрева - не ниже 400oC.1. The method of separation of gold from gold-containing raw materials, which consists in the fact that the starting material is mixed with a reagent that contains alkalis (NaOH, KOH), the mixture is heated to a melt state and kept in a heated state, after which the melt is treated with water, filtered with separation of the precipitate and gold is recovered, characterized in that LiOH is also used as alkali, the reagent also includes nitrate (NaNO 3 , NaNO 2 , KNO 3 , KNO 2 ) in a mass ratio of alkali: nitrate from 1: 1 to 6: 1 , mass ratio of reagent to the source material take at least 2.5: 1, and the heating temperature is not lower than 400 o C. 2. Способ выделения золота по п.1, отличающийся тем, что осадок перед извлечением золота обрабатывают раствором соляной или азотной кислоты. 2. The method of gold recovery according to claim 1, characterized in that the precipitate is treated with a solution of hydrochloric or nitric acid before gold recovery. 3. Способ выделения золота по п.1, отличающийся тем, что после выщелачивания водой осадок подвергают вторичной плавке в присутствии щелочей и повторно обрабатывают водой и фильтруют. 3. The method of separating gold according to claim 1, characterized in that after leaching with water, the precipitate is subjected to secondary smelting in the presence of alkalis and re-treated with water and filtered. 4. Способ выделения золота по п.1, отличающийся тем, что расплав выдерживают в нагретом состоянии не менее 1 ч при температуре нагрева 400oC.4. The method of gold extraction according to claim 1, characterized in that the melt is kept in a heated state for at least 1 hour at a heating temperature of 400 o C.
