Chrome Plant Optimisation: Small Changes, Big Recovery Gains

In chrome beneficiation, recovery losses rarely come from one big failure — they accumulate across the circuit. Mis-set spiral splitters, worn cyclones and drifting feed densities each shave fractions of a percent that add up to real money at the end of the month.

A structured optimisation programme starts with a metallurgical audit: sampling campaigns, mass balances and particle-size-by-size recovery analysis. From there, targeted interventions — re-cut spirals, cyclone upgrades, reagent and wash-water tuning — typically unlock two to five percentage points of recovery without major capital.

LUMEACON's operational excellence team designs and optimises chrome, gold, iron ore, platinum and coal plants. Our Lean Six Sigma approach means improvements are measured, locked in and sustained — not one-off fixes that drift back.
