目前,在我国金属矿石的浮选中应用最为广泛的起泡剂是2号油。但是,2号油的主要原料松节油供应日益困难。为了改变起泡剂的原料结构,生产高效、低毒、价廉的起泡剂是必要的。株洲选矿药剂厂研制了一种新型起泡剂新松醇油。至今已有四十余家矿山使用新松醇油,均获得稍好于2号油的技术经济指标。新松醇油是一种棕色油状液体,比重约为0.944;经气相色谱分析主要成分为α萜烯醇、桉叶素、环己醇、环戊醇等。鱼类毒性和小白鼠急性毒性半数致死量的测定表明,新松醇油、2号油对鱼类的安全浓度分别为0.8784ppm,0.7437ppm。按《公害与农业》一书所载标准判断,均属中
At present, the most widely used foaming agent in the flotation of metal ores in our country is No.2 oil. However, turpentine supply, the main raw material of No. 2 oil, is increasingly difficult to supply. In order to change the raw material structure of the foaming agent, it is necessary to produce a foaming agent of high efficiency, low toxicity and low cost. Zhuzhou beneficiation pharmaceutical factory developed a new type of foaming agent Xin song alcohol oil. So far, more than 40 mines have been used Xin Song alcohol oil, have received slightly better than the 2 oil technical and economic indicators. Xinsong alcohol oil is a brown oily liquid, the specific gravity of about 0.944; by gas chromatography the main components of α-terpene alcohol, cineole, cyclohexanol, cyclopentanol and so on. Fish toxicity and acute toxicity of mice measured by the median lethal dose showed that the new pine oil, the safety of the oil on the 2nd concentration of fish were 0.8784ppm, 0.7437ppm. According to “pollution and agriculture,” a book contained in the standard judgment, are in
