系统地介绍了钨矿选矿技术的现状,分别详细介绍了白钨矿、黑钨矿以及黑白混合钨矿的选矿工艺的进展及方向.白钨矿的传统加温浮选由于环境的恶劣,逐渐被环境良好的常温浮选方法取代,而且常温浮选方法工艺简单、操作方便,越来越受到矿山的欢迎;黑钨矿摒弃了传统的单一重、浮、磁工艺,目前采用的重、浮、磁联合工艺流程正逐渐趋于完善,随着高效率设备离心机以及高梯度磁选机的出现,钨细泥的选矿得到了很大的提高;随着钨矿的开采殆尽,传统的单一浮选已经不能满足低、贫、杂的黑白混合钨矿,多种经典的新工艺不断涌现出来;选冶联合流程针对那些品位低,难处理的钨矿具有良好的效果,是今后钨矿发展的重要方向.
繫統地介紹瞭鎢礦選礦技術的現狀,分彆詳細介紹瞭白鎢礦、黑鎢礦以及黑白混閤鎢礦的選礦工藝的進展及方嚮.白鎢礦的傳統加溫浮選由于環境的噁劣,逐漸被環境良好的常溫浮選方法取代,而且常溫浮選方法工藝簡單、操作方便,越來越受到礦山的歡迎;黑鎢礦摒棄瞭傳統的單一重、浮、磁工藝,目前採用的重、浮、磁聯閤工藝流程正逐漸趨于完善,隨著高效率設備離心機以及高梯度磁選機的齣現,鎢細泥的選礦得到瞭很大的提高;隨著鎢礦的開採殆儘,傳統的單一浮選已經不能滿足低、貧、雜的黑白混閤鎢礦,多種經典的新工藝不斷湧現齣來;選冶聯閤流程針對那些品位低,難處理的鎢礦具有良好的效果,是今後鎢礦髮展的重要方嚮.

This paper introduces the current situation of tungsten processing technology by discussing the processing technology progresses and directions of scheelite, wolfrmite, and scheelite-wolfrmite mixed ore respectively. Scheelite flotation technology at room temperature, for its eco-friendliness, simple technique and convenient operation, has gradually replaced the heating flotation. The combined processing technology of gravity concentration, flotation and magnetic separation has been operated on wolframite. The processing rate of tungsten fine mud has been greatly improved with the application of centrifuges and high gradient magnetic separators. The traditionally singled flotation fails to process the low-grade and miscellaneous scheelite-wolfrmite mixed ore with reduced tungsten reserve. Thus, new processing technologies have been invented, such as the combined technology of processing and smelting.
