| titleOfInvention | A kind of thick aurin smelting method |
| abstract | The present invention relates to a kind of thick aurin smelting methods, and specific step is as follows：(1) thick gold nitric acid solution digestion, is obtained by filtration filter residue I；(2) potassium nitrate is added in filter residue I, is roasted after mixing, obtains fired slags；(3) potassium hydroxide solution digestion is added in fired slags, filter residue II is obtained by filtration；(4) by the nitric acid digestion of filter residue II, filter residue III is obtained by filtration；(5) hydrochloric acid is added in filter residue III and filtrate is obtained by filtration in hydrogen peroxide reaction, handle, obtain bronze.For bronze purity after being refined using this method 99.99% or more, which overcomes the general wet process-disadvantage that pyrogenic process combination product purity is not high, smelting temperature is high, process flow is complicated, the period is long. |
