In order to have different criteria for evaluating performance of the algorithms in this study, synthetic target were created from the pure spectral signature of alunite
with various degrees of mixture (f= 10%, 20%, 30%, 40%, y 100%).
Potential non-bauxite sources for alumina in the United States might include clay, alunite
, and anorthosite (Bray 2014).
2008): Silcrete and alunite
genesis in alluvial palaeosols (late Cretaceous to early Palaeocene, Duero basan, Spain).
and kaolinite can be uniquely identified by their spectral characteristics (position and shape of absorption troughs between 2.
The advanced argillic alteration is characterized by an assemblage of Amorphous silica + cristobalite + alunite
+ tridymite + kaolinite + quartz + jarosita + sulfur; although, in some cases some of the mentioned minerals are absent.
Finally, certain minerals found predominantly in altered areas, including halloysite, siderite and alunite
, [3, 17], have been used to identify subsurface reservoirs.
Larsen (1942a) reported the presence of alunite
in the Clay Canyon deposit, as rounded, creamy white to dark gray nodules up to 20 cm in diameter, incorporating about one third of their weight in quartz.
The equation for the acid dissolution of alunite
His mount, Alunite
, found stablemate, Narrative, ridden by John Carroll, too good in a competitive mile and a quarter handicap.
The former was a Gowran Park maiden winner for John Oxx at two, and took to the dirt surface well, despite worries beforehand, beating Dettori's mount Alunite
His mount, Alunite
, found stablemate, Narrative, too good and then previous winner, Seba, went down to another stable companion, Infinite Spirit.
In Azerbaijan, the Dashkesan iron (includes cobalt) and Zaginsky alunite
(aluminium) deposits were developed with the establishment of kombinats for refining and primary processing.
