Product Description

Detailed Specifications & Features

Metallurgical Grade Fluorspar Lump & Concentrate ≥65% CaF₂ | Cost-Effective Flux for Steelmaking

2. Product Introduction

Our metallurgical grade fluorspar is available in both lump and concentrate forms, serving as an essential fluxing agent for steelmaking and non-ferrous metal processing. Sourced from natural fluorspar ore, it is processed through crushing, screening or flotation to deliver a stable CaF₂ content of ≥65%, with strictly controlled impurities including SiO₂, S, P and As.

The hard, well-sized lumps can be directly charged into furnaces, while the evenly graded concentrate is ideal for automated batching systems. With consistent fluxing performance that effectively lowers slag melting points and improves fluidity, this cost-effective industrial raw material is widely used in steelmaking, ironmaking and non-ferrous smelting. We support bulk exports and long-term stable supply.

3. Core Advantages

Effective Fluxing to Optimize Smelting Conditions

With CaF₂ ≥65%, this fluorspar significantly reduces slag melting point, improves fluidity, and enhances desulfurization and dephosphorization capabilities. It minimizes refractory lining erosion, extending furnace service life. The stable fluxing effect shortens smelting cycles, boosts production efficiency, and cuts fuel consumption, making it a balanced choice for metallurgical processes.
Dual Forms for Versatile Process Compatibility

We offer two specifications to suit different production needs:

Lump: Uniform particle size, low dusting, suitable for direct charging into conventional furnaces.
Concentrate: Good flowability, easy metering, ideal for automated batching in modern steel plants.

Both forms undergo rigorous impurity control, allowing flexible selection based on your working conditions.

5. FAQ

Q1: What are the applications of fluorspar lumps vs. concentrates?

A: Lumps are primarily used in traditional smelting processes such as blast furnaces and converters, requiring no pre-treatment. Concentrates are more suitable for electric arc furnaces, refining furnaces, and automated batching systems where precise metering and mixing with other powders are required.

Q2: What are the benefits of the ≥65% CaF₂ grade?

A: This is the industry standard grade for metallurgical use, delivering excellent fluxing performance to lower slag melting points and improve fluidity. Compared to higher grades, it meets process requirements while offering significant cost advantages, making it ideal for steel mills seeking efficiency and cost savings.

Q3: Are sulfur and phosphorus impurities properly controlled?

A: All batches are produced in compliance with metallurgical fluorspar standards, with S ≤0.2% and P ≤0.03%. This prevents harmful elements from compromising steel quality, ensuring stable smelting processes and consistent final product quality.

Q4: Can lump size or concentrate fineness be adjusted?

A: Yes. We can adjust the particle size distribution of lumps or the mesh size of concentrates within industry specifications to better match your equipment and process requirements.

Q5: Can you guarantee stable long-term export supply?

A: With stable ore resources and established production lines, we maintain year-round mass production with consistent batch-to-batch quality. We support full container exports and long-term contracts to meet the continuous production needs of overseas customers.
