溶剂萃取技术的发展,很大程度上取决于萃取剂的发展。对重有色金属来说更有赖于要求高效能、低溶解度,原料充足且价格低廉的萃取剂。环烷酸就是具有这样特性的一种新型萃取剂。近几年,随着我国石油工业的飞速发展,环烷酸为其石油付产品,来源极其丰富。因此,我们以系办工厂为基地,选环烷酸作萃取剂,改革工厂现有脂肪酸萃取水溶度大、除铜不净而加铁粉置换铜的复杂工艺。经萃取后,使其含量在Cu≤0.002％,Fe≤0.001％达到
The development of solvent extraction technology depends largely on the development of extractant. For heavy non-ferrous metals is more dependent on the requirements of high performance, low solubility, adequate raw materials and low cost extractant. Naphthenic acid is a new type of extractant with such characteristics. In recent years, with the rapid development of China’s oil industry, naphthenic acid is the most abundant source of oil for its products. Therefore, we have to do the factory as a base, selected naphthenic acid as extractant, the existing reform of existing fatty acid plant extract water solubility, in addition to the net copper and iron powder replacement copper complex process. After extraction, the content of Cu ≤ 0.002%, Fe ≤ 0.001% achieved
