从金属与非金属采矿工业的发展趋势来看,要求处理低品位矿石的数量将不断增大。因而,在浮选回路中采用先进的大容积的单槽浮选机的兴趣日益增长。由于大浮选机的研制成本相当高,因此,用现有小型号浮选机的经验是很重要的,这样可以使大型浮选机结构在现场改造的工作量为最小。本文对使用小型浮选机经验转换成1000立方英尺(28.3立方米)吸气式浮选机的 R 和 D制法进行了评论。主要是对内槽流体动力学原理以及槽到液面和泡沫控制的依据进行评论,并对样机的工厂试验做出总结。
According to the development trend of the metal and nonmetal mining industry, the quantity of ore that is required to deal with low grade ore will continue to increase. As a result, there is an increasing interest in using advanced high volume single tank flotation machines in flotation circuits. Because large flotation machines are quite expensive to develop, it is important to use the experience of existing small-scale flotation machines to minimize the need for large-scale flotation machines to be rebuilt in the field. This article reviews the R and D approaches that have been empirically converted to 1,000 cubic feet (28.3 cubic meters) aspirating flotation machines using small flotation machines. Mainly on the tank hydrodynamics and tank to the liquid level and foam control basis for comment, and the prototype factory test summary.
