Sishen mine. Sishen mine, is near the town of Kathu in the Northern Cape Province. Sishen is our flagship operation and one of the largest open pit mines in the world some 14km long. Sishen mine has sufficient reserves to sustain a 14-year life of mine. The bulk of our iron ore production comes from Sishen mine, with most of it being exported.
2020-7-7 KUMBA IRON ORE Cover: At Kumba’s new Kolomela Mine, the pit is starting to emerge as waste is moved to expose the ore body. In 2009, 4.0Mt of waste material was moved as the mine prepares for first production in 2012 and full production of 9Mtpa in 2013. The mine is on schedule and on budget and will produce direct-shipping ore for export.
MINAS-RIO One of the world’s largest iron ore projects, when it was developed. Minas-Rio in Minas Gerais state in Brazil is a fully integrated export iron ore operation, with the mine, beneficiation plant, 529km slurry pipeline and dedicated export facility at the port of Açu.
Iron ore is the key component in steel, the most widely used of all metals. In South Africa our iron ore operations are made up of a 69.7% shareholding in Kumba Iron Ore Limited (Kumba), a leading supplier of seaborne iron ore. Kumba is listed on the Johannesburg Stock Exchange and operates three mines.

Ultrasound is known to enhance solid/liquid reactions. This paper deals with the investigation of the dissolution of phosphate rock in nitric acid, in the absence and presence of ultrasound.
2019-10-24 This research aims to explore the effect of ultrasound irradiation as a pretreatment method on the reverse flotation of phosphates. Ultrasonic treatment was used prior to flotation at various ultrasound intensities. The feed sample containing 10.34% P2O5 and 48.01% CaO was obtained from Lar mountain located in southwest of Iran.
