Common Iron Ore Extraction Processes. Different types of iron ore use different exraction process, especially when the magnetism various. Let's see more about common iron ore extraction processes!
Get PriceMining and processing of iron oreinvolves coarse crushing and screening. Iron ore is beneficiated by crushing and then separating the iron from the gangue minerals through screening. This is usually so efficient that lower grade ore can be treated especially when the magnetite is quite coarse.

Get PriceIron ore is the key raw material for steel production enterprises. Generally,iron ore with a grade of less than 50% needsto be processed beforesmeltingand utilization. Aftercrushing,grinding,magnetic separation,flotation, andgravity separation, etc., iron is gradually selected from the natural iron ore.
Get PriceMost iron ores are extracted by surface mining. Some underground mines do exist, but, wherever possible, surface mining is preferred because it is cheaper.Lumps and fines Crushing. As-mined iron ore contains lumps of varying size, the biggest being more than 1 metre (40 inches) across and the smallest about 1 millimetre (0.04 inch).
Get PriceMagnetized drums collect magnetic material, so it can be further concentrated (magnetite iron minerals content). The lighter particles that were separated during the spiral gravity separation step are rolled into balls (combined with bentonite or a similar binding agent) and cooked in an induction oven. This process is known as pelletization.
