Research on the Mineral Processing Technique of Recovery for Refractory Oxidized Antimony from Tailings
As is known, the oxidized antimony and antimonate are hard to treat. A new combined mineral processing flowsheet which is controlled in grinding and classification -bulk floatation-gravity separation is adopted to dispose of gravity-separated tailings (antimony content: 1.48%; oxidization rate: 68.92%) in Muli Antimony Mine, the grade of floatation antimony concentrates is 32.64%; the grade of gravity-separated antimony concentrates is 26.99%; the combined grade of floatation and gravity-separated antimony concentrates is 30.85%, and the total recovery of antimony is 70.64%.Adopting the new mineral processing technique have solved the problem of over grinding of antimony ore by controlling grinding and classification, recovering effectively the sulfide antimony and the easy floatable oxidized antimony of fine size by bulk floatation, recovering effectively the oxidized antimony which is hard to float by classified gravity separation. This is a great breakthrough in the mineral processing technique of the recovery of the oxidized antimony. At present, favorable economic benefit has been obtained from the application of this processing technique in Muli Antimony Mine.
