Abstract: Structural characteristics of new type centrifugal machine produced by a company was introduced, and this machine was used in the study of recovery technology of tungsten fine deposit, a lot of discarding tailings of tungsten fine deposit was realized. The research indicated, on the condition of feed ore concentration 20%,ore feeding speed 4 L/s, centrifuge speed 600 r/min, water addition 2 L/min, tungsten fine deposit which the WO₃ grade was 0.22%,through the separation of centrifugal machine, tungsten rough concentrate with WO₃ grade 0.65% and recovery rate 74.18% could obtained.

Key words: New type centrifugal machine, Tungsten fine deposit, Technological parameters
