Chrome Ore Washing vs. Concentrate Plants – What’s the Difference?

/in /by

Chrome ore can be upgraded in two distinct ways. Choosing the right flow sheet depends on the feed grade, particle size, and market requirements.

1. Chrome Ore Washing Plant
Purpose: Upgrade high-grade, coarse ROM (run-of-mine) ore to marketable lumpy chrome (>10 mm).

Basic flow:

Primary crushing (only when ROM >250 mm)
Rotary scrubber – removes sticky clay and disintegrates ore
Jig Machine – gravity separation of +10 mm fraction
Hand sorting / stockpiling – final lumpy product
Key benefits:

Produces lumpy chrome, the most sought-after product on the market.
Minimal grinding → lower capital and power costs.
Quick pay-back; ideal for small- to mid-scale miners with high-grade deposits.

2. Chrome Concentrate Plant
Purpose: Liberate and recover fine-grained chrome from lower-grade or disseminated ores.

Basic flow:

Crushing & milling – reduce feed to <1 mm
Spiral chute (roughing + cleaning) – gravity concentration
Dewatering & drying – prepares 40–48 % Cr₂O₃ concentrate for export or ferrochrome smelters
Key benefits:

Higher final grade because particles reach complete (monomer) liberation.
Suitable for ores with substantial silica or gangue that cannot be removed by simple washing.
Produces a uniform, low-moisture concentrate ready for container shipment.
