Abstract: To obtain high quality mineral processing products,the various mineral processing process and equipment are continous being updated and improved.The continuous development of mineral efficient gravity separation equipment development is especially important in the mineral processing for its green and environment advantage of gravity separation.Based on the research status of spiral chute sorting in China,the mining chute sorting process is discussed.According to some application practices of metal gravity separation chute,the application status of spiral chute gravity separation process is summarized,and the problems in spiral chute application are analyzed,provide support for development of gravity separation equipment in mineral processing.

Key words: Spiral chute, Gravity separation, Analysis
