摘要
浮选是当前白钨矿选别的主要手段之一。文章结合选矿实践及有关白钨矿浮选技术,介绍了白钨矿的基本性质及其浮选药剂的应用现状和发展情况,结合文献报道,分析了有关药剂在反应过程中的作用机理。指出目前白钨矿浮选难点主要在于使目的矿物与含钙盐类矿物有效分离,以及捕收剂选择性的提高等方面。针对白钨矿加温浮选技术存在能耗高等问题,认为常温浮选法及其药剂的开发是今后研究的重点,提出加大对有关药剂作用机理的研究,以及寻求在新药剂、组合药剂的开发与应用上的突破,是白钨矿浮选药剂的发展方向。
Flotation is one of the main means of for the beneficiation of scheelite. Based on the beneficiation practice and related flotation technologies, this article introduced the basic properties of scheelite, the application status and development situation of flotation reagents by analyzing the mechanism of reagents in the reaction process. The current flotation technology is characterized by the ineffective separation of the targeted minerals from calcium-containing salt minerals, and the improvement of the selective capacity of collector agents. To overcome the disadvantage of high energy consumption in the heated scheelite flotation Technique, we put forward that flotation at the room temperature and the development of flotation reagents be the future research focuses. The development direction of scheelite flotation reagents, such as the development and breakthrough of new reagents and composite regents, is also forecasted.
