Goethite containing 46 to 56 wt Fe is the primary iron mineral of interest in this deposit. Oolitic ironstones typically contain between 30 and 50 wt Fe. Oolitic iron formations are, however, much more aluminous and contain high concentrations of phosphorus P an average of 0.5 to 1 wt than banded non-oolitic iron formations.

57 Summary Spindle-shaped goethite particles are produced by oxidizing iron carbonate intermediates in the presence of growth regulators or by changing the flow rate of oxidizing gas during oxidation. Thus, the resulting goethite particles have a narrow size distribution, high aspect ratio and are substantially dendrite free. These properties make the inventive goethite particles suitable ...
