Grootegeluk 6 (GG6)

A critical source of both A-grade, export-quality coal and power station coal

Grootegeluk 6 (GG6)

Project Overview


With production at the site expected to commence in 2020, the new GG6plant will enable an additional 600 tonnes per hour of throughput o‌n the ROM feed, as well as higher, more valuable yields through enhanced operational efficiencies and better beneficiation processes.


The plant will produce a primary A-grade (typical 6000 kcal/kg) export product at approximately 1.7 Mtpa. Construction o‌n the project began in Q2 and is expected to be completed by Q2 2020


The existing Grootegeluk 2 (GG2) plant historically produced power station coal. The project will convert the single-stage beneficiation plant to a new double-phase beneficiation plant, namely Grootegeluk 6 (GG6). Technical alterations at the plant consist of:


  • A new Small Coal Beneficiation Plant (SCP), enabling the processing of fragments of less than 10mm
  • Improving Fines Plant beneficiation processes through the use of Reflux Classifier technology
  • A Dewatering plant and ancillaries
  • Expansion of the current stockyard


A new double-stage, 1 700 dense medium separation (DMS) plant will be established to process and prepare the RB1 export coal. The plant will also include a fines beneficiation Reflux Classifier circuit and dewatering section. The existing GG6 stockyard will be upgraded and expanded to accommodate additional product volumes.


The approved project start-up capital requirement, in nominal terms, for the GG6 Expansion Project amounts to R4.8bn. The spend to date Dec-18 amounts to R 2,101 million.
