3.5 Limonite (FeO(OH)·nH₂O) Appearance: Limonite is typically brown, yellow, or ochre-colored, with an earthy texture. Properties: It has a hardness of 4-5.5 and forms as a product of weathering. Formation: Limonite forms through the oxidation and weathering of iron-rich minerals like hematite and magnetite.

Limonite closely related to clay minerals and the shape are irregular, gelatinous, granular, veined. It often presents symbiotically as matrix-coated hematite, magnetite, or chrome spinel. A small amount of limonite exists along the edge of the pyrite. Moreover, some of these sulfide minerals could be observed.

Limonite is sometimes formed in large quantities by the weathering of the sulphides of iron; such gossan has occasionally been used as an iron ore. At Bannockburn, in the Madoc area, a pyrite deposit was discovered below the limonite, which was being mined as an iron ore; this gossan capping of the pyrite was from eight to fifteen feet deep.

In order to separate the limonite from the saprolite, some suitable laterite ore deposits may be selectively mined to first remove the upper limonite fraction and then separately mining the lower saprolite ore. Alternatively, where the separation of the limonite and saprolite is poorly defined, the whole ore may be mined and either processed as ...
