What we do

Built around the wash plant

Processing is the core of the business. Ore sourcing and distribution wrap around the plant, so clients deal with one counterparty from feed to delivered tonne.

Chrome ore washing and processing

Our plant turns variable run-of-mine feed into a stable chromite concentrate that meets smelter and export specification. Crushing, wet screening and gravity separation on spiral concentrators lift the Cr2O3 grade and strip out silica and waste, and every parcel leaves with a certified assay.

Feed preparation
  • Primary crushing of oversize
  • Wet screening to circuit size
  • Feed blending to a target grade
Spiral concentration
  • Rougher and cleaner spiral banks
  • Gravity separation of chromite from silica
  • Middlings recycled, tailings managed
Dewatering and stockpile
  • Dewatering to dispatch moisture
  • Stockpiles held by grade band
  • Independent assay on every parcel

Ore sourcing

Run-of-mine chrome ore bought from contracted producers in Gauteng and the surrounding areas. We do not operate our own mines. Feed is secured under supply agreements and quality is controlled at the plant gate.

  • Contracted producers only
  • Supply agreements with agreed grade bands
  • Sampling and grade control on receipt

Distribution

Managed logistics from stockpile to buyer. Weighbridge-controlled loading, road haulage to smelters, and delivery to rail sidings for the export corridor.

  • Side-tipper and interlink fleets
  • Rail siding and port coordination
  • Load-by-load documentation

How it works

Five steps from ore to delivery

Every tonne follows the same route, with a sample and a weighbridge ticket at each hand-over point.

Receive

Run-of-mine ore from contracted producers is weighed, sampled and graded as it arrives at the plant.

Crush and screen

Oversize is reduced and feed is classified so the wash circuit receives a consistent size range.

Wash

Spiral concentrators separate chromite from silica and waste, lifting grade and lowering contaminants.

Stockpile and assay

Concentrate is dewatered, stockpiled by grade and assayed by an independent laboratory.

Dispatch

Parcels are loaded over the weighbridge and delivered by road or rail with full documentation.

Product

Washed chrome concentrate

Our standard product is a washed chromite concentrate suited to ferrochrome smelting and the export market. Grade, sizing and moisture are agreed per contract and confirmed by assay on every parcel.

About Chroma

A Gauteng chrome processor built around one clean chain

Chroma Mining (Pty) Ltd is a South African chrome processing company headquartered in Midrand, Gauteng. We buy run-of-mine chrome ore from contracted producers in Gauteng and the surrounding areas, wash and process it into a consistent concentrate, and deliver it on time and on specification.

Keeping sourcing, processing and distribution under one roof removes the hand-over losses that erode margin in the chrome trade. Our clients deal with one counterparty, one set of documents and one accountable team.

Specification first

Every parcel is assayed by an independent laboratory before it is invoiced.

Weighbridge discipline

Loads are weighed in and out, and tickets travel with the consignment.

Reliable dispatch

Committed tonnages are scheduled against fleet and siding capacity, not promised on hope.

Compliance

Operations run within South African mineral processing, environmental and transport regulations.
