Abstract The presence of tenacious froth in flotation products has a detrimental effect on the downstream dewatering process, which is a challenge in processing plants of a range of commodities, such as coal, talc, molybdenum, bitumen, potash, zinc, copper and gold. The generation of tenacious froth is not only related to the properties of mineral particles but can also be affected by water salinity and the presence of clay minerals. In this article, the effects of stable froth on the dewatering of flotation products were presented. Froth properties including froth structure, froth stability and froth rheology were presented first and then recent studies on the influence of froth on dewatering process were reviewed. Finally, future directions of research to increase the dewatering efficiency of flotation products are recommended.

泡沫特性对浮选产品脱水的影响——批判性评论

摘要 浮选产品中存在顽固的泡沫会对下游脱水过程产生不利影响，这对煤炭、滑石、钼、沥青、钾肥、锌、铜和金等一系列商品的加工厂来说是一个挑战。顽固泡沫的产生不仅与矿物颗粒的性质有关，还可能受到水盐度和粘土矿物存在的影响。本文介绍了稳定泡沫对浮选产品脱水的影响。首先介绍了泡沫特性，包括泡沫结构、泡沫稳定性和泡沫流变学，然后回顾了最近关于泡沫对脱水过程影响的研究。最后，推荐了未来提高浮选产品脱水效率的研究方向。
