Abstract: From the hot alkali water examination on oil sands-KBK oil sand and LWL oil sand-from the Indonesia PT.Karunia Alam Indonesia industry, the result shows that the separate effect is low, when use “organic solvent extraction + hot water extraction” technology to separate oil from oil sand, the separate effect is high. The percent of oil recovery from oil sand is 96.9% and 97.81%, and the tail sand accords with the nation emission standard.

Key words: Oil sand, Extraction, Separation, Solvent extraction, Water washing

摘要： 　对印尼ＰＴ．Ｋａｒｕｎｉａ　Ａｌａｍ　Ｉｎｄｏｎｅｓｉａ公司的ＫＢＫ和ＬＷＬ两个油砂矿的油砂进行分离研究，实验结果表明：ＫＢＫ和ＬＷＬ的油砂热碱水水洗抽提分离效果较差，利用“萃取＋水洗”两部分离工艺进行油砂分离试验效果很好，油砂油的收率分别达到９６．９％和９７．８１％，尾砂满足国家排放标准。
