What this grade is for

Natural and processed lump material for steelmaking, non-ferrous smelting, ferroalloys, and other flux applications.

Lumps are a practical choice when the buyer wants coarse feed, lower dust, and a simpler charging path without converting the material into powder first.

  • Steelmaking and non-ferrous fluxing where coarse feed is preferred.
  • Ferroalloy and metallurgical charging applications.
  • Buyers who want a natural or processed lump form with published grade options.

Published specification guidance

Use the table below as a buyer-facing starting point. Final chemistry, moisture, particle size, packaging, and inspection terms should still be confirmed in the sales contract.

Buyer checklist

Before you issue an RFQ, make the request precise enough for the plant and the logistics team to quote the same thing.

  • Confirm whether the buyer wants natural or processed lumps.
  • State the target CaF2 band and the maximum impurity levels.
  • Explain the furnace or smelting process so the seller can quote the right lump behavior.
  • Include size range, inspection terms, and destination port in the RFQ.

Common questions

Why do some buyers prefer lumps instead of powder?+

Lumps are often easier to handle, create less dust, and fit charging systems that are designed for coarse feed.

Do lumps still need impurity control?+

Yes. Even coarse material needs the right CaF2 band and impurity profile for the end process.

Can lumps be used in non-ferrous metallurgy?+

Yes, when the charging method and process chemistry are aligned with coarse material.
