摘要
以陕西卡林型金精矿为研究对象,进行了提取液浓度、温度、搅拌浸出时间及固液比对腐殖酸提取和测定的影响研究。研究结果显示,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。
The effec of extract concentration, temperature,leaching time, and solid-liquid ratio t on extraction and determination for humic acids were carried out in Carlin-type gold. The result revealed that with the increasing of al- kali concentration and temperature, desulfurization reaction of pyrite was promoted, so high humic acid content de- termination result. High solid-liquid ratio could lead to low content of humic acids during determination. The leac- hing time was reduced with alkali concentration increasing.
