| Abstract Scope |
The flotation process is used to concentrate the zinc ore, willemite. That process stage produces a residue consisted of hematite and dolomite. This work aims through the density separation to concentrate the mineral phase hematite. The vibrating table was used to process 500g of material. The separation process presented three fractions with different densities. To characterize the fractions, ICP, SEM-EDS and XRD analysis were used. In denser fraction the XRD shows the hematite intensity greater than in the initial sample, indicating the concentration of the mineral phase. Different from other fractions that presented lower intensity. The ICP in denser fraction had an iron content of 40.4%, higher than the initial sample of 7%. The SEM-EDS also presented an iron content increasing from 7% to 44.5%. Therefore, density separation is an alternative that adds value to the material, reducing tailing volume in mine industry. |
