| Abstract: | With acid hot-pressure oxidation pretreatment,the gold recovery rate of a certain refractory gold concentrate is raised from 35.6% to 94.3%,comparing to the ordinary leaching process.The influence of temperature,time,pulp density,oxygen partial pressure,material grade on cyanidation extraction rate was researched.What's more,the influence of jarosite product on silver recovery rate was discussed. |
