摘要:
为了研究棉油、大豆油、蓖麻油、玉米油等几种植物酸化油在温度20℃下的浮选性能，采用气相色谱法分析了其脂肪酸的组成, 通过浮选试验评价了其性能.结果表明，这几种植物酸化油中，含有脂肪酸的组成不同，大豆与玉米酸化油的不饱和脂肪酸亚油酸,亚麻酸含量较高，而棉油酸化油主要含有油酸与亚油酸、无亚麻酸，蓖麻油主要是羟基油酸.不同植物酸化油捕收剂的浮选性能不同，它们的浮选性能低于油酸.这几种植物酸化油捕收能力是棉油酸化油＞大豆酸化油＞蓖麻酸化油＞玉米酸化油；而大豆酸化油与玉米酸化油捕收剂的选择性相当，但高于棉籽油酸化油和蓖麻油酸化油.因此，作为捕收剂应选用不饱和脂肪酸特别是亚油酸和亚麻酸的含量高的酸化油，有利于胶磷矿的浮选.
Abstract:
The froth flotation tests were conducted to study the flotation performance of acidified vegetable oil such as cottonseed acidic oil, soybean acidic oil, castor acidic oil and corn acidic oil, at the 20℃. And its fatty acid composition was determined by gas chromatography. The results show that the composition of fatty acid in this several acidified vegetable oil is different, soybean acidic oil and corn acidic oil rich in unsaturated fatty acids with high linoleic acid and linolenic acid contents, while cottonseed acidic oil mainly contains oleic acid and linoleic acid, no linolenic acid and castor oil main ingredients for hydroxyl acid. The floatability of this several acidified vegetable oil is also different which is weaker than oleic acid. In unit of acidified vegetable oil, the collection capacity of cottonseed acidic oil is better than soybean acidic oil, castor acidic oil and corn acidic oil, while the selective of soybean acidic oil which is equal to corn acidic oil is better than cottonseed acidic oil and castor acidic oil. So, it is better for the flotation of collophanite as the plant acidic oil with higher content of unsaturated fatty acids especially containing linoleic acid and linolenic acid selected as collector.
