removing iron ore from copper concentrate

Removal of sulfur in the reduction of iron-ore In lean coal and lignite, sulfur is predominantly present as organic compounds. According to experiments with a QMC-230 mass spectrometer and an IR absorption analyzer, the removal of sulfur in the reduction of iron-ore concentrates is hindered by the adsorption of sulfur-bearing gases and itsCopper Mining and Extraction Sulfide Ores,From the formula, it is clear that iron and sulfur have to be removed in order to produce copper. The roasting process: changes some of the CuFeS 2 to copper oxide; removes some of the sulfur as sulfur dioxide; This is done by heating the concentrated ore from froth flotation. It is heated to between 500 °C and 700 °C in air.Removal of Sulfur From Iron Ore with Physical and Chemical,,For the process of sulfur removal with H2O2 solution, approximately 40 g of iron ore was weighed at 0.001 g accuracy and put in a 400 mL Erlenmeyer flask in a way that the “amount of ore (g)/volume of H 2 O 2 solution (mL)” ratio will be approximately 1/5.
