| 摘 要： | 采用陕西卡林型金精矿,研究了提取液浓度、温度、搅拌浸出时间及固液比对腐殖酸提取和测定的影响。结果显示,提取剂浓度,浸出温度、时间及固液比对腐殖酸的提取及测定有明显的影响。增加碱浓度和提高浸出温度可促使黄铁矿的脱硫反应,使腐殖酸含量测定结果偏高；固液比增大,使腐殖酸提取量降低,使腐殖酸含量测定结果偏低；碱浓度的增加,可减少搅拌浸出时间。

| Abstract: | The effect on extraction and determination for humic acids of extract concentration, temperature, leaching time, and solid-liquid ratio were carried out in Carlin-type gold. The result revealed that with the increasing of alkali concentration and temperature, desulfurization reaction of pyrite was promoted, so high humic acid content determination result. High solid-liquid ratio could lead to low content of humic acids during determination. The leaching time was reduced with alkali concentration increases. |
