本文叙述关于矿浆密度、充气量和搅拌速度影响泡沫浮选的研究成果，试样是用磨过的石英和金的混合物，在实验室小规模进行的。其中金的粒度范围从中粒（0．15mm）到粗粒（1．0mm）。研究结果表明调节变量对回收粗粒金以及改过粗粒和细粒金的选择性很重要。业已证明，如果不考虑浮选机中存在的紊流，则有效地回收金的上限粒度（0．7mm，回收率＞80％）和一些理论模型相一致。 This paper describes research results on the effect of slurry density, aeration rate, and agitation speed on froth flotation, performed on a small scale in a lab using a mixture of milled quartz and gold. The gold particle size range from medium (0.15mm) to coarse (1.0mm). The results of the study indicate that the manipulated variables are important for the recovery of coarse-grained gold and the selectivity of coarse and fine grained gold. It has been shown that the upper limit grain size (0.7 mm, recovery> 80%) that effectively recycles gold is consistent with some theoretical models, irrespective of the turbulence present in the flotation machine.
