SUMMARY:Simandou
DESCRIPTION:The prospect of mining the world class iron deposits on the Simandou Range in the SE of Guinea, is becoming a reality as negotiations on the infrastructure progress with the JV partners. Blocks 3 & 4 of the Simandou deposit held by Rio Tinto Simfer – a joint venture between Rio Tinto, China Iron Ore Holdings (a Chinalco-led consortium of Chinese SoEs) and the Government of Guinea – covers two major deposits named Pic de Fon and Ouéléba, striking roughly 7km each, in a north south direction along the Simandou Range. 

Work is being undertaken to develop a greater understanding of the geology, genesis and mineralisation of the project to assist in the realisation of the resource and maximisation of  value. The increasing geological knowledge presented in this paper will provide an understanding of impacts on the chemistry and physical characteristics of the material mined, processed, agglomerated, and smelted. 

Teamwork involving geologists, miners, chemists and metallurgists has been conducted to help us understand the impact of the geology on downstream processing requirements to meet the diverse future needs of clients i.e. steelmakers. 

A comprehensive test programme of work has been developed in order to test and prove Simandou ores as suitable feed-stock for both Blast Furnace (BF) and Direct Reduction (DR) processes.  This paper presents promising results obtained at lab scale on Ouéléba ore that show acceptable physical and chemical properties in both sintering and pelletizing for both BF and DR routes. The results of laboratory characterisation and basket tests for the DR shaft process on a sample of Ouéléba DR pellet were also positive, and an assessment of DR pellets based on Pic Du Fon ore ongoing.
