Froth stability is an important factor in determining flotation yield, and one of the factors affecting froth stability is dependent on the concentration and type of surfactant. Since detergents contain different types of surfactants, it is possible that they affect the froth stability (together with the frothing agent and the collector) and consequently the flotation yield. Therefore, the effect of detergents containing lauryldimethylamine oxide and sodium laureth sulphate was investigated in this study. The results showed that the addition of detergents increased the froth stability by more than 30% and 45% in terms of froth formation and froth decay, respectively. The flotation tests also showed that the addition of detergents increased the sulphur content of the concentrate by about 0.7%.

洗涤剂对泡沫稳定性和浮选分离的影响

泡沫稳定性是决定浮选收率的重要因素，而影响泡沫稳定性的因素之一取决于表面活性剂的浓度和类型。由于洗涤剂含有不同类型的表面活性剂，它们可能会影响泡沫稳定性（连同起泡剂和捕收剂），从而影响浮选率。因此，本研究研究了含有月桂基二甲胺氧化物和月桂基聚醚硫酸钠的洗涤剂的效果。结果表明，在泡沫形成和泡沫衰减方面，添加洗涤剂分别使泡沫稳定性提高了 30% 和 45% 以上。浮选试验还表明，加入清净剂可使精矿的硫含量增加约 0.7%。
