Liberation Size and Work Index of Kurungu Iron Ore Deposit, Kogi State, Nigeria

Authors: Ihogbetin FF, Asuke F, Mohammed RA

ABSTRACT

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 test sample (Kurungu iron ore) collected from different pits was homogenized, pulverized and sieved using the shaking machine. The various sieved size fractions of the ore were analyzed using X-ray Fluorescence (XRF), and the liberation size was determined to be 250 μm containing 45.33% Fe. The work index was calculated to be 13.96 kWh/t. Hence the liberation size and energy required for comminution has been established for the Kurungu Iron ore.
