摘要
在实验室中直接从矿样中提取和分离了腐殖酸。可溶性富啡酸不仅可从矿石中萃取金,而且可溶解金、银。在酸性条件下沉淀的凝胶状胡敏酸对金、银具有强烈的吸附作用。实验研究表明,腐殖酸是金银的聚集体,是金成矿中重要的有机地球化学因素。
Humic acid was directly extracted and separated from ore samples in the laboratory. So-luble fulvic acid can extract gold and silver from auriferous ore, and dissolve them. Colloidalhumic acid is strongly capable of absorbing gold and silver. Experimental study has shownthat humic acid, as an important organic geochemical factor involved in gold mineralizationmay play a role in accumulating gold and silver in the exogenic process.
