摘要:
以癸酸为原料,通过酯化反应和羟肟化反应,合成了直链羟肟酸类捕收剂癸酸羟肟酸钠,并用红外光谱、元素分析和显色反应对其进行了结构表征和纯度检测. 以癸酸羟肟酸钠作捕收剂,对湖北黄石某低品位白钨矿(WO3 0.40%)进行了浮选应用研究. 在浮选工艺采用浮选脱硫铜、常温粗选脱硅和升温精选脱钙镁的浮选流程. 结果表明,获得的精矿品位51.29%WO3,回收率77.28%的选矿指标. 相对于传统捕收剂,品位相当,回收率提高了3%.
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%.
