摘要：
The present invention provides a method for removing an iron content in a petroleum series mineral oil therefrom which comprises treating a petroleum series mineral oil fraction containing 5 ppm or more of the iron content by the use of a high gradient magnetic separator under conditions of the strength of a magnetic field being from 500 to 25,000 gauss, a temperature being from room temperature to 400.degree. C., and a linear velocity being 0.1 to 50 cm/second.
