| 摘 要： | 通过红外光谱等手段研究苯甲羟肟酸与黑钨矿作用机理，认为苯甲羟肟酸对黑钨矿的捕收作用，主要是与黑钨矿表面的Mn^2 生成五元螯合物，以化学吸附为主，Mn^2 是黑钨矿的主要浮选活性中心。

| Abstract: | A study on the action mechanism between benzyl hydroxamic acid and wolframite by infrared spectroscopy suggested that the collecting action of benzyl hydroxamic acid to wolframite is based on the formation of a chelate compound with five|membered ring on the surface of wolframite, dominated by chemical adsorption. It is believed that Mn+{2+} is the main flotation active center of wolframite. |
