1. Chemical Composition

The chemical composition varies depending on the ore source and smelting process (high-carbon vs. low-carbon). Typical ranges are as follows:

Note: High-carbon ferrochrome slag typically contains higher Cr₂O₃ than low-carbon slag.

3. Environmental & Safety Specifications

4. Main Application Fields

• Civil Engineering: Road base, subgrade material, backfill.

• Construction Materials: Iron corrective raw material for cement production, concrete aggregate, blocks, and bricks.

• Refractory Materials: Raw material for producing magnesia-chrome or chrome-magnesia bricks.

• Agriculture & Soil Improvement: Utilizes its alkalinity to neutralize acidic soil and provides secondary nutrients like magnesium and silicon.

• Abrasive Industry: Raw material for manufacturing abrasive sand.

• Recycling: Recovery of micro-alloy particles from high-grade slag.

6. Packaging, Storage & Transportation

• Packaging: Usually in bulk. Fine powder can be packaged in ton bags.

• Storage: Should be stacked on hardened, impermeable ground; recommended to have a roof to reduce rainwater erosion and dust.

• Transportation: Use dump trucks or sealed tankers to prevent spillage and dust.

7. Health & Safety

• Dust: Dust may be generated during handling; long-term inhalation may harm the respiratory system. Dust suppression measures and dust masks are required during operation.

• Skin Contact: Wear gloves; avoid prolonged skin contact.

• Environmental Risks: Cr(VI) leaching concentration must be strictly controlled to ensure compliance with environmental regulations during use and disposal, preventing soil and water contamination.
