本文研究了关于磨矿环境对浮选中细粒（-10μm）矿物回收率影响的已发表的和新的实验证据。讨论了使用完全电化学惰性研磨介质从矿石中提高高价值矿物回收率的原因，这与研磨介质产生的氢氧化铁表面污染的减少有关。搅拌研磨技术允许使用完全惰性的研磨介质，在初级研磨应用中的应用可能会导致浮选粗选应用中精矿回收率的增加。研磨介质的作用对于细颗粒很重要，并且随着研磨尺寸变得更细而逐渐变得更加重要，这表明研磨介质的作用主要是由于在细颗粒的生产中矿物与研磨介质的磨损机制。讨论了研究和行业应用的机会。
This paper examines published and new experimental evidence on the effect of the grinding environment on fine (−10μm) value mineral recovery in flotation. Reasons for increases in fine value mineral recovery from ores with fully electrochemically inert grinding media are discussed in relation to reduced surface contamination by iron hydroxide emanating from the grinding media. The application of stirred milling technology, which allows the use of fully inert grinding media, to primary grinding applications may lead to increased fine value mineral recovery in flotation rougher applications. It is suggested that the effect of the grinding media, which is important for fine particles and progressively becomes more important as the grind size becomes finer, is principally due to the abrasion mechanism of the minerals with the grinding media in the production of fine particles. Opportunities for research and industry application are discussed.
