Abstract

Abstract

With the decrease of high quality ore resources as well as the continuous increase of environment demand for production, it becomes feasible and significant to enhance the precise regulation to the separation process using the compound force field of centrifugal force and gravity. Spirals have been found many varied applications in mineral processing over numerous years, as well as the theoretical research results are also very rich. Combining the previous work by the authors and the related research developments at home and abroad, the significant problems were discussed in details, including the flow characteristics in spirals, the particles motion behaviors, relevant measurement approach and the influence of structural and operational parameters on spirals performance. Finally, the emphases and directions of spirals research were brought forward.
