摘要:
为了研究不同植物脂肪酸组成对胶磷矿常温浮选的影响，选取了棉油、豆油、米糠油、棕榈酸、硬脂肪酸等几种植物脂肪酸，采用气相色谱法分析了其脂肪酸的成分,利用浮选试验评价了其性能.试验结果表明，这几种植物油含有脂肪酸的成分不同，浮选性能也不同.常温下的浮选性能依次为：碘值135棉油脂肪酸＞碘值110豆油脂肪酸＞碘值95米糠油脂肪酸＞碘值120棉油脂肪酸；浮选时，棕榈油脂肪酸与硬脂酸完全没有泡沫.植物脂肪酸捕收剂中的亚油酸／油酸比值对选别指标的影响为：比值越大，浮选效果越好.温度较低时，应选用不饱和脂肪酸特别是亚油酸和亚麻酸的含量高脂肪酸作为捕收剂.
Abstract:
Cottonseed fatty acid, soy fatty acid, rice bran fatty acid, palm oil fatty acid and stearic acid were selected to study how the composition of plant fatty acid effected froth flotation of collophanite at normal temperature. The froth flotation tests were conducted to research the flotation performance of plant fatty acid and its fatty acid composition was determined by gas chromatography. The results show that the composition of fatty acid and flotation performance of these several plant fatty acids are different. The floatability in unit of different vegetable fatty acid at normal temperature is iodine value 135 cottonseed fatty acid＞iodine value 110 soy fatty acid＞rice bran fatty acid ＞iodine value 120 cottonseed fatty acid. Palm oil fatty acid and stearic acid do not cause foaming in flotation process. The effect of L/O ratio in unit of different plant fatty acid on the ore dressing indexes is better for the flotation of collophanite when plant fatty acid with higher L/O ratio. So, unsaturated fatty acids especially containing linoleic acid and linolenic acid should be selected as collector when flotation temperature is relatively low.
