Removal of Sulfur From Iron Ore with Physical and Chemical,
Abstract - In this study, sulfur was removed from Kahramanmaras Elbistan iron ore, which has a high sulfur content, by application of microwave and chemical methods (H 2SO 4 / H 2O2) together. Low-grade iron ore, with a high sulfur content, constitutes a significant bottleneck especially in technical applications.
Copper 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.

Sulphur removal in ironmaking and oxygen steelmaking
sulphur needs to be removed, to typi-callybelow0.015%.Themainsourceof sulphur in the BF-BOF steelmaking processcomesfrom coke. Eventhough roughly 40% of the sulphur in coal is removed in the coking process, typical sulphur levels in coke remain around 0.5%. Iron ore contains typically 0.01% sulphur and is only a minor source of
copper extraction and purification - chemguide
Purification of copper. When copper is made from sulphide ores by the first method above, it is impure. The blister copper is first treated to remove any remaining sulphur (trapped as bubbles of sulphur dioxide in the copper - hence "blister copper") and then cast into anodes for refining using electrolysis. Electrolytic refining
