Major Mines & Projects | Ramu Mine

Nickel is apparently enriched in both saprolite and rocky saprolite, but cobalt is only enriched in the saprolite. The principal ore minerals identified in the Ramu deposit include goethite, asbolan and garnierite. Goethite is found as ochre-coloured, porous, cryptocrystalline, needle-like matrix in the limonite and saprolite zones of the laterite.

Mineralogical Characterization of Limonitic Laterite from …

The gold in limonitic laterite exists in native gold, followed by electrum and silver gold mine. The complicated distribution characteristics of gold minerals are closely related to limonite, chromite spinel, silicate minerals. Some of the gold minerals exist as monomers. 23.30% of gold minerals are embedded in or enclosed in the silicate minerals.

Limonite

In the Dahlonega gold belt in Lumpkin County, Georgia gold was mined from limonite-rich lateritic or saprolite soil. The gold of the primary veins was concentrated into the limonites of the deeply weathered rocks. In another example the deeply weathered iron formations of Brazil served to concentrate gold with the limonite of the resulting soils.

INCO R&D: Goro Laterite Development

The laterite nickel ore at Goro is composed of two layers–limonite and saprolite–between a cover of leached material and the bedrock below. The 10-20-m-thick cover has its own two layers: brittle iron oxide crust covers a high-hematite zone. Beneath these is the 10-m-thick limonite layer, which grades about 1.5% Ni.
