Investigation on the Purification of Dolomite from Phosphate Tailings by Flotation
Phosphate tailings through Flotation contains large amount of dolomite which is difficult to be separated from apatite.In this present research,phosphate tailings is recycled by Flotation i.e.re-processing.High-purity dolomite with purity as high as 91.17% is seperated,which contains 19.82% of MgO.The results of orthogonal test show that the effect of various levels of different factors on the high-purity dolomite floatated.Future utilization of purified dolomite is also discussed: magnesium fertiliser especially magnesium phosphate is expected to be an ideal product from high-purity dolomite.
