Experimental study on beneficiating difficult dressing of antimony oxided in Dongan Antimony Mine

Based on process mineralogy of ore samples in Dongan antimony mine, the present study analyzes the occurrence and ore characteristics of oxide antimony. Considering the mine's actual realities of production and comparing pilot programs, gravity separation- flotation process on complex recovery of difficult dressing antimony oxidized ore are introduced. Tests are focused on the study of fine- grained oxide antimony ore flotation pilot by selecting CX- 1 as the collector antimony oxide fuel to help carry out flotation collector antimony oxide minerals. This technology has effectively solved the problem of difficult dressing antimony oxided,thus the resources are fully utilized and the economic efficiency of the enterprise is increased.
