  • PYRITE ROASTING, AN ALTERNATIVE TO SULPHUR BURNING M

    The major objective of the roasting process is to eliminate the sulphur contained in the concentrate and to provide a calcine product and SO2 containing gases A roasting temperature of 6001,000°C is generally the most suitable range, depending on the process and mineralogical requirements As the sulphur content of the sulphide concentrate is primarily pyrite (FeS2), the followingA high quality iron oxide concentrate, suitable as a feed for blast and electric reduction furnaces was recovered from highsulfur and lowgrade pyrite cinder Pyrite cinder was treated with a hot strong alkali solution which dissolved most of the silica and alumina, leaving a solid residue and forming a precipitate which was an acidsoluble salt of aluminosilicate hydrate The residue andRecovery of iron oxide concentrate from highsulfur11/03/2018· The sulfur content of concentrate was decreased from 287 to 066%, with an aluminum to silicon ratio (A/S) increasing from 336 to 443 Keywords Highsulfur bauxite Flotation Al 2 O 3 recovery Sulfur content This is a preview of subscription content, log in to check access Notes Acknowledgements The authors acknowledge the financial supports of the National Science Fund ofFlotation Separation of Pyrite from Refractory High

  • CNA Method for producing highgrade

    The invention relates to a method to produce high grade sulfur concentrate by using low grade pyrite ore, which takes pyrite ore containing 8 percent to 25 percent sulfur as raw material which is smashed and milling ground to allow the pyrite ore to be dissociated from rocky mineral monomer Ore slurry is arranged on spiral chute to obtain rough concentrate with the sulfur containing gradeThe major objective of the roasting process is to eliminate the sulphur contained in the concentrate and to provide a calcine product and SO2 containing gases A roasting temperature of 6001,000°C is generally the most suitable range, depending on the process and mineralogical requirements As the sulphur content of the sulphide concentrate is primarily pyrite (FeS2), the followingPYRITE ROASTING, AN ALTERNATIVE TO SULPHUR BURNINGBest Selling High Sulfur Pyrite For Sulfuric Acid , Find Complete Details about Best Selling High Sulfur Pyrite For Sulfuric Acid,Prices Pyrite,Iron Pyrite,Pyrite Ore from Iron Ore Supplier or ManufacturerLuoyang Dan Ding Import And Export Trading Co, LtdBest Selling High Sulfur Pyrite For Sulfuric Acid Buy
