Chrome Ore Logistics South Africa — Mine to Ferrochrome Plant Tracking

South Africa holds 72% of the world's chrome ore reserves — almost entirely within the Bushveld Igneous Complex. The country produces 16–18 million tonnes of chrome ore annually, with the majority converted to ferrochrome domestically. South Africa is the world's largest ferrochrome producer, supplying the global stainless steel industry.

Chrome ore moves from mines in the Bushveld — Limpopo, North West, and Mpumalanga — to ferrochrome smelters in Emalahleni, Middelburg, Rustenburg, and Steelpoort. This network of mine-to-plant road movements is substantial, and largely unmonitored.

Chrome Ore Logistics Risk Profile

Chrome ore at R400–800/tonne (UG2 and Metallurgical Grade) may appear low-value — but volumes are enormous. A ferrochrome plant consuming 800,000 tonnes of chrome ore annually at 3% pilferage loses 24,000 tonnes = R9.6–19.2 million per year.

More critically: grade fraud is rampant in South African chrome logistics. Cr2O3 percentage determines chrome ore value — UG2 tailings (26–28% Cr2O3) have significantly lower value than metallurgical grade ore (42–46% Cr2O3). Substitution of low-grade for high-grade material during transit costs ferrochrome plants far more than quantity losses.

Key Chrome Corridors

Steelpoort valley (Limpopo) → Middelburg / Emalahleni ferrochrome plants: 150–250 km hauls on the R37 and N11. High frequency — 100–300 trucks/day per plant.

Rustenburg area mines → local ferrochrome smelters: Short-haul, very high frequency. Close proximity to informal chrome buyers near Rustenburg industrial zones.

Zeerust / Mafikeng area → North West smelters: Longer-haul chrome movements with limited surveillance coverage.
