简单介绍了接触荷电的原理，综合阐述了涡轮荷电（Tutbocharger）分选机。对不同矿石，特别是北非含有碳酸盐脉石的原矿、印度含有黄铁矿的原矿和安哥拉含有石英质脉石的矿样都获得了成功的结果，并进行了讨论。强调了分选器充电装置的中间电极表面温度的显著影响，间歇试验和连续试验的结果都表明，无论从技术角度看还是从经济角度看，本方法是很有工业应用前景的，甚至不亚于泡沫浮选。
The principle of contact charge is briefly introduced, and the Tutbocharger separator is comprehensively described. Successful results have been obtained and discussed for different ores, in particular the carbonate ore with carbonate gangue in North Africa, the ore ores with pyrite in India and the quartz igneous rocks in Angola. Emphasized the significant influence of the intermediate electrode surface temperature of the separator charging device. The results of the batch test and the continuous test both show that this method is promising in industrial applications, both technically and economically In the froth flotation.
