Flotation Iron Ore And Sulphur In The Iron Ore

For low grade iron ore, smelting costs and resource wastage will be increased. Product quality of such ore is affected adversely by an excessive amount of sulfur. This also causes environmental pollution. In accordance with the vanadium titanium (V Ti) magnetite concentrate properties with low iron grade and high sulfur content, the joint process of magnetic separation and flotation was.
