Spiral classifier uses the principle of the proportion different of solid particles, so the precipitation speeds is also different in the liquid. Fine mineral particles float in the water and overflow; the coarse ore particles settle on the bottom of the channel. Material is discharged from the upper by spiral, so as to finish the grading work.

Siderite is one of the common iron ores. The iron grade of siderite (FeCO 3) is low, and the theoretical iron grade is only 48.20%.Some of them also contain Mg and Mn. Moreover, siderite is weakly magnetic iron ore, most of the siderites are fine-grained and complex in composition, and belong to refractory iron ore resources.
