gold bearing limonite gossans

Characterization of an iron oxy/hydroxide (gossan type ...

Gold was observed to be present as native and electrum (6–24 µm in size) and associated with limonite, goethite and lepidocrocite within calcite and quartz matrix. Mineral liberation analysis (MLA) showed that electrum is found as free grains and in association with beudantite, limonite/goethite and quartz.

limonite pseudomorphe

Limonite precipitated in rock that did not formerly contain any iron-bearing sulfide. Gold-bearing Limonite: A gold-bearing variety of limonite. Common in gossans of gold deposits. Indigenous limonite: Sulfide-derived limonite that remains fixed at the site of the parent sulfide, often

Limonite - Uses of Limonite

These gossans were used by prospectors as guides to buried ore. In addition the oxidation of those sulfide deposits which contained gold, often resulted in the concentration of gold in the iron oxide and quartz of the gossans. Goldbearing limonite gossans were productively mined in the Shasta County, California mining district.

Mineralogy and Geochemistry of Limonite as a Weathering ...

2018-5-22  Limonite is mainly derived from weathering of Fe sulfide, iron-bearing carbonate, or silicate minerals. The weathering of Fe sulfide or carbonate minerals to yield limonite from the Tongling mineralization cluster has been studied extensively. Knowledge of the mineralogical and geochemical characteristics of the limonite from weathering of Fe-bearing silicate minerals is still incomplete ...
