Guangxi High-Calcium Limestone - High-Quality Flux for Steelmaking

CaO＞54%, low  magnesium& phosphorus, specialized for steel mills

CaO＞54%, low  magnesium& phosphorus, specialized for steel mills

ㅤPRODUCT DETAILS

Guangxi's limestone mines offer exceptional natural quality, characterized by high purity and low impurities. They are primarily used in steel plants as steelmaking flux, sintering ingredient, and desulfurizer.

High Calcium Oxide Content

Run-of-mine (ROM) CaO content exceeds 54%, with extremely low levels of harmful impurities such as phosphorus (P) and sulfur (S), effectively ensuring molten steel purity.

High Reactivity
High reactivity after calcination, reacts quickly in converters, shortening smelting time.


Improved Steelmaking Efficiency
Enhances desulfurization and dephosphorization efficiency, shortens the smelting cycle.

 

Reduced Production Cost
High-grade ore reduces limestone consumption and waste residue discharge.

Improved Steel Quality
Extremely low sulfur and phosphorus impurity levels help significantly improve the purity and mechanical properties of finished steel.

 

Vast Resource Reserves
Predicted total resources exceed 8 trillion tons, with proven reserves exceeding 3 billion tons, including large-scale mines with tens to hundreds of billions of tons.

Favorable Location and Transportation
Located in South China facing ASEAN, with access to Qinzhou Port, Fangchenggang Port, and railway lines. High cost-performance products are expanding into overseas markets.
