Through eight managed coal mines, Exxaro produces 40Mtpa of power station, steam and coking coal. All power station coal is supplied to the national power utility, Eskom, and municipal power stations. Grootegeluk is one of the most-efficient mining operations in the world, and operates the world’s largest coal beneficiation complex. A robust pipeline of greenfield and expansion projects will result in Exxaro remaining one of the largest coal producers in South Africa. Exxaro also produces char and related products for the rapidly growing ferroalloys industry.
