characterisation of an iron ore resource is critical to effective project evaluation, process design, risk management and project execution. SGS collaborates with major, global iron ore producers and consistently delivers accurate metallurgical test work results. SGS has recently completed the expan-sion of its state-of-the art iron ore testing
The liberation size and work index of Kurungu iron ore deposit located in Ajaokuta Local Government Area of Kogi State, Nigeria was determined in this study. Samples were collected from the ore site and prepared for sieve analyses and testing. The modified Bond work index method was used to determine the work index, using granite with known work index as the reference ore.
The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example, the finer the grind size desired, the higher is the kWh/t required to grind to that size. Magdalinovic [38] measured the Bond work index of three ore types using different test screen sizes. He produced a correlation between the mass of test screen undersize per revolution, G, and ...

Smelting involves heating up ore until the metal becomes spongy and the chemical compounds in the ore begin to break down. Most important, it releases oxygen from the iron ore, which makes up a high percentage of common iron ores. The most primitive facility used to smelt iron is a bloomery. There, a blacksmith burns charcoal with iron ore and ...
The Australian iron ore industry was also born in South Australia. Iron ore has been shipped from the Middleback Ranges near Whyalla since 1903, and steel since 1941. Today, South Australia is a better position than ever to work with potential domestic and/or global partners requiring iron ore and/or its derivatives.
