摘要
Abstract
Decanoate hydroxamic acid was synthesized by the esterification reaction of capric acid and following oximation reaction. Structure and purity of the product were characterized by infrared spectroscopy,elemental analysis and color reaction. It was used in flotation of Huangshi's low grade scheelite. The flotation processes comprise roughing desulfuration,room temperature desilication,warm decalcification and de-magging. The results show that tungsten concentrate grade and recovery rate are 51.29%and 77.28%,respectively. Compared with using the traditional fatty acid collector,the recovery rate increases by 3%.关键词
