Iron Ore Beneficiation Testwork | SRK Consulting
For West African type deposits, SRK 's experience is that there is no guarantee of successfully developing a viable flowsheet. Ores can often respond to gravity and/or magnetic separation. However, due to the presence of lower-iron content, iron minerals such as goethite, mass yields and recoveries to high grade concentrates can be low.
