Iron ore extraction is mainly performed through open pit mining operations, resulting in significant tailings generation. The iron ore production system usually involves three stages mining, processing and pelletizing activities. Of these, processing ensures that an adequate iron grade and chemistry is achieved prior to the pelletizing stage.
Steel mills that process iron ore are located in Gauteng, Mpumalanga, KwaZulu Natal and the Western Cape. South Africa has well-established infrastructure network that is geared towards the extractive industry and supports the beneficiation of minerals extracted in South Africa. The country has the largest railway network in Africa.
MINING AND PROCESSING Iron ore mining can be broadly divided into two categories namely 1 manual mining which is employed in small mines and 2 mechanized mining is suitable for large iron ore mines.
