China manufacturer supply directly calcium ferrite with low price

Calcium ferrite slag arises from their high capacity to absorb acidic impurities (e.g., arsenic and antimony) while presenting a wide, homogeneous liquid area when mixed with iron oxides. These two aspects partly solve troublesome magnetite precipitation during the smelting and converting of copper concentrates and reduce bath contamination in the electrolytic refineries.

Calcium ferrite is used as deoxidizer, desulfuration, dephosphorization in steelmaking. which can rise refining effective highly and ladle' using time.
