Abstract:

In order to utilize mineral resources effectively and maximize the benefits，research of separation flotation and ore blending flotation to various types of ores which fed into the process of Linglong concentration plant was introduced in this paper.And the results showed that under the current conditions of technique and economy it was feasible for this flotation method to deal with highly-oxidized low-grade residual ore from upper middle.By using the current flotation technology，the flotation index would not be affected if the amount of residual ore fed into the flotation circuit was less than 30 percent of the total amount of ore.The research findings were applied to actual production in the year of 2011，the number of the processed residual ore was 273 thousands tons，the grade of residual ore was 1.1×10-6 and the grade of concentrate was 76.89×10-6，and the flotation recovery rate was 95.26%.Tremendous economic benefits of more than 50 million yuan was obtained in that year.

Key words: highly oxidized, low-grade, residual ore, flotation, ore blending, recovery rate
