limonite saprolite gold

Limonite

One of the first uses was as a pigment. The yellow form produced yellow ochre for which Cyprus was famous, while the darker forms produced more earthy tones. Roasting the limonite changed it partially to hematite, producing red ochres, burnt umbers and siennas. Bog iron ore and limonite mudstones are mined as a source of iron, although commercial mining of them has ceased in the United States.

Laterite-saprolite Au USGS

DESCRIPTION: Au disseminated in laterite and saprolite that developed under conditions of tropical weathering (fig. 32) over a wide variety of bedrock types but distal to known bedrock gold deposits. Figure 32. Idealized cross section of laterite-saprolite

Saprolite

Saprolite (from Greek σαπρος = putrid + λιθος = rock) is a chemically weathered rock (literally, it means "rotten rock"). More intense weathering results in a continuous transition from saprolite to laterite. Saprolites form in the lower zones of soil horizons and represent deep weathering of the bedrock surface. In lateritic regoliths– regoliths are the loose layer of rocks that rest on the bedrock saprolite may be overlain by upper horizons of residual laterite; most of the original profile is preserved by residual soils

Limonite Uses of 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.

Home An Introduction in Laterite

In the tropics the laterite cover around outcropping gold-quartz-veins often shows a pronounced gold dispersion halo which can be traced by geochemical exploration. It is proved that the primary gold is partially moved in solution and re-precipitated in secondary gold particles with lower grain size and reduced Ag content.

Nickel Laterites: The World’s Largest Source of Nickel

Jun 12, 2014 The saprolite and limonite zones tend to contain the higher grades of Ni and can range from 1.5-3% and 1.2-1.7% respectively. How do they form? Many factors affect the formation of nickel laterites, including the original rock the soil develops from, the climate, the rate in which weathering occurs, drainage of groundwater and the tectonic setting.

US6680035B2 Atmospheric leach process for the recovery

A hydrometallurgical process is provided for leaching nickeliferous laterite ores at temperatures below the boiling point of the pulp and at atmospheric pressure. The high iron fraction of the laterite, referred to as limonite, is first contacted with concentrated sulfuric acid to partially or completely dissolve the iron and nickel into solution.
