【Abstract】 The technological process of ore washing-screening-magnetic separation has been applied in Guangdong Provincial Dading Mine for the treatment of iron minerals and three qualified iron concentrates with different particle sizes have been obtained. In this process, coarse particles are directly subjected to dry magnetic separation so that the cost for grinding can be greatly reduced and the investment for mine construction can be saved.更多还原
