Shaking tables, spiral chutes, and magnetic separators, etc., are often used for reprocessing concentrate with either weak magnetic separation or strong magnetic separation to further enhance the grade of chrome concentrate and the ratio of chrome to iron. In addition, some mines may also opt for flotation and flocculation flotation methods.

The commonly used re-election primary mineral processing process involves: grinding the chrome ore fines to a reasonable fineness, then cleaning and grading the ore mixture by utilizing the different settling speeds of solid particles in a liquid through a spiral classifier. Subsequently, the material is washed and selected using a jig or shaker, and transported to a spiral chute for sorting fine-grained ore powder.
