It seems there might be some confusion in your question. Iron ore is a naturally occurring mineral deposit rich in iron oxides (like hematite or magnetite), while limestone is primarily composed of calcium carbonate (CaCO₃). You cannot directly “make” iron ore from limestone, as they are fundamentally different materials. However, limestone does play a role in iron and steel production as a flux to remove impurities during smelting.
If you’re asking about processing iron ore using a vibrating screen, here’s how it works:
Role of a Vibrating Screen in Iron Ore Processing:
1. Crushing & Screening:
– After mining, raw iron ore is crushed into smaller pieces.
– A vibrating screen separates the crushed ore into different size fractions (e.g., lump ore vs. fines).
– Oversized material may be sent back for further crushing.
2. Beneficiation (Optional):
– Screens help classify ore before processes like magnetic separation or flotation to increase iron content.
3. Pelletizing/Sintering Feed Prep:
– Screens ensure uniform particle size for sintering (agglomeration) or pelletizing.
Limestone in Iron Production:
– Limestone is added to the blast furnace as a flux to react with impur
es (e.g., silica), forming slag (calcium silicate), which is removed.
Misinterpretation Clarification:
If you meant processing limestone to extract iron:
– Limestone itself contains negligible iron unless it’s an iron-bearing limestone (rare).
– For low-grade iron sources, specialized processes (like reduction roasting) might be used, but vibrating screens alone won’t “create” iron ore.

Key Takeaway:
– A vibrating screen is used to size and separate iron ore during processing, not to chemically transform limestone into iron ore.
– If you need details on a specific process (e.g., screening parameters or beneficiation), clarify your goal!
