Optimising the Recovery of Fine and Coarse Particles in Mineral Flotation

通过气泡收集细（<10微米）和粗（>100微米）矿物颗粒是选择性泡沫浮选工艺的核心。在矿物浮选中，仅在澳大利亚，细粒和粗粒价值矿物的损失就相当于每年约5亿美元。 浮动对澳大利亚经济的重要性可以从以下事实来判断：2001年矿产和能源行业的商品出口额超过390亿美元，2005年上升到750亿美元以上（澳大利亚统计局）。 这些行业生产我们的行业合作伙伴特别感兴趣的精矿，如铜、镍、锌和煤。

The collection of fine (<10 microns) and coarse (>100 microns) mineral particles by gas bubbles is the very heart of the selective froth flotation process. In the flotation of minerals, losses of fine and coarse value minerals equate to approximately $500M annually in Australia alone. The significance of flotation to the Australian economy may be judged from the fact that over $39b in commodity exports was derived from the minerals and energy industries in 2001, rising to well over $75b in 2005 (Australian Bureau of Statistics). These industries produce mineral concentrates of specific interest to our Industry Partner, such as copper, nickel, zinc and coal.
