对陕西某含砷含碳难浸金精矿进行了酸性压力氧化—氰化浸金试验研究,考察了磨矿细度、矿浆浓度、初始硫酸用量、温度、氧化剂用量、氧分压等因素对浸金效果的影响.在适宜条件下,试验获得了理想的技术指标,金氰化浸出率达到97.10%.
對陝西某含砷含碳難浸金精礦進行瞭痠性壓力氧化—氰化浸金試驗研究,攷察瞭磨礦細度、礦漿濃度、初始硫痠用量、溫度、氧化劑用量、氧分壓等因素對浸金效果的影響.在適宜條件下,試驗穫得瞭理想的技術指標,金氰化浸齣率達到97.10%.
대협서모함신함탄난침금정광진행료산성압력양화—청화침금시험연구,고찰료마광세도、광장농도、초시류산용량、온도、양화제용량、양분압등인소대침금효과적영향.재괄의조건하,시험획득료이상적기술지표,금청화침출솔체도97.10%.
Experimental researches on a refractory gold concentrate containing arsenopyrite and carbon from Shaanxi were carried out with the acidic pressure oxidation -cyanide leaching of gold.The influence of grinding fine-ness,pulp density,initial dosage of sulfuric acid,temperature,oxidant dosage and oxygen partial pressure on pressure oxidation-cyanide leaching process was investigated .A good gold recovery (97.10 %) was obtained on proper condi-tions.
