煤焦油在选矿企业上应用的特点在于它有复杂的馏份,根据我们初步研究,各馏份按共性质不同在浮选上都具有各种不同的作用,有综合利用的必要和可能。另一方面,它的使用方法不同于常用的化学捕收剂如黄药等,主要是高沸点馏份的产物例如重油、蒽油因其粘度大又难溶于水,致使应用方法复杂化。我们采用低温及高温煤焦油馏份对辉锑矿作系统地浮选试验,自取原料,自行加工(我局中心试验室),经数月的研究试验获得了一些成就,根据已取得的试验成果证实,除硫化蒽油具有良好的捕收性能外,还初步摸索出其他馏份的捕收性能、起泡性能以及它们具体的几种使用方法,特别是在研究过程中,发现了低温煤焦油有可能不经分馏与硫化直接用于浮 The application of coal tar in beneficiation enterprises is characterized by its complex fractions. According to our preliminary study, different fractions have different effects on flotation according to the common properties, and have the necessary and comprehensive utilization. On the other hand, its use is different from the commonly used chemical collectors such as xanthophylls and the like, and the products of mainly high-boiling fractions such as heavy oil and anthracene oil complicate the application method due to their high viscosity and poor solubility in water. We use low temperature and high temperature coal tar distillate fisanthsite for systematic flotation test, take the raw materials, self-processing (Bureau of the central laboratory), after several months of research and obtained some achievements, according to the test has been made The results show that, in addition to good anthracite anthracene oil collection performance, but also initially explored the other fractions of the collection performance, foaming properties and their specific methods of use, especially in the study found that low-temperature coal It is possible for tar to be floated directly without fractionation and vulcanization
