Multi-response and Misplacement Optimization of Upgrading ...

2021-7-29  Taguchi-designed experiments were conducted, to study the amenability of the use of liquid–solid fluidization for upgrading the lean-grade iron ore. Taguchi design uses orthogonal arrays to study the statistical interpretation of importance of operating parameters on the mean and variation of responses [23,24,25].

Upgrading Nigerian iron ores SpringerLink

A number of Nigerian iron ore deposits have been upgraded to the specifications of concentrates for the blast furnace and the direct reduction iron- and steel-making plants. Depending on the mineralogy of the ore deposits, the techniques of oil agglomeration, magnetizing reduction, washing and scrubbing, gravity concentration, and reverse froth flotation have been utilized.
