Abstract:
    The present invention relates to the non-ferrous ore milling and separating process. The process includes sieving the crude ore into three size fractions, including 4 mm over fraction to the ore mill for milling to 3 mm below size, 2-4 mm fraction to the jigger for enriching and 2 mm below fraction to the screw chute system for enriching and to the table floating system for separating; milling crude ore in the crude ore mill; enriching in the jigger; grading after milling; separating in the table floating system and the screw chute system to obtain ore concentrate; and milling the concentrated tailings to recover target metals before draining ore slag. The present invention has sufficient milling and high metal recovering rate.
