Reduction roasting of limonite ores: effect of ...

The Caron process is most effective when applied to high goethite limonite ores (De Graff, 1979, Canterford, 1975, Power and Geiger, 1977). Saprolite or silicate-rich laterite minerals tend to undergo phase transformation that results in poor metal recoveries when treated with this process ( Kukura et al., 1979, Stevens et al., 1975 ).

Lateritic nickel ore deposits - Wikipedia

This ore is so rich in limonite (generally grading 47% to 59% iron, 0.8 to 1.5% nickel and trace cobalt) that it is essentially similar to low-grade iron ore. As such, certain steel smelters in China have developed a process for blending nickel limonite ore with conventional iron ore to produce stainless steel feed products.
