Geomagnetic field data processing is involved in many aspects. In practical work,according to characteristics of abnormal geomagnetic field and geological issues to cope with,we must focus on key technology for data process-ing. This paper introduced application of key technologies in geomagnetic field data processing for a known ore dis-trict,such as reduction of curved surface into a horizontal plane,downward continuation,and separation of local field and background field. The application of these three key technologies has brought good geological result.
