山苍籽油酸是由山苍籽核仁油加工而得,其蒸馏温度是220～340℃,酸值大于170,碘值大于55.2,皂化值大于165,未皂化和不可皂化物小于1.67％,凝固点15℃。采用山苍籽油酸,在浮选湘西白钨矿的试验中,取摇床尾矿,经磨矿后作浮选给矿,其品位WO_3为0.69％,浮选精矿含WO_3为40.15％,作业回收率达90.16％,此成果应用于生产,可使目前生产中白钨矿的总回收率提高2～3％。
Sesamia oleifera is obtained from the processing of the kernel of kaffir seed kernel oil, the distillation temperature is 220 ~ 340 ℃, the acid value is greater than 170, the iodine value is greater than 55.2, the saponification value is greater than 165, unsaponifiable and unsaponifiable matter is less than 1.67% , Freezing point 15 ℃. In the test of flotation of scheelite in western Hunan, shale tailing was taken and flotation was given to ore after grinding. The grade of WO3 was 0.69%, the concentration of WO3 was 40.15% Operating recovery rate of 90.16%, the results applied to the production, the current production of scheelite in the total recovery rate increased by 2 to 3%.
