For the sulfur fertilisers, plant yield relative to the control increased slightly for jarosite and alunite
and more than trebled for gypsum for the 240 mg S/pot application (Fig.
Other associated minerals are: nitratine, montmorillonite, paratacamite, atacamite, gunningite, alunite
The Rahy colt looks the sort to have on your side in a scrap, and he picked up well and sped on in good style from Alunite
and Slip Stream.
In laboratory leaching studies he reported the following sulfates: jarosite, alunite
, melanterite, copiapite and yavapaiite.
Caroll went on to complete a double when Godolphin's Alunite
made all in the one-mile maiden.
Unidentified white, massive minerals of the alunite
group occur as late-stage hydrothermal gangue in several veins.
is shaping up quite nicely, and he shared company with another who will hopefully be making waves in the shape of Equerry.
is a widespread and common mineral in the central core of the deposit, and is readily recognized by its pale pink to rose-pink color.
The bladed and spear-shaped crystals reach 4 mm in size, and occur as attractive clusters on what looks like tan-colored dolomite or alunite
crystal-lined vugs and seams.
The mineralogy and geochemistry of this gossan have been described by Nickel (1982), who noted the occurrence of a number of secondary ore minerals including malachite, azurite, chrysocolla, pseudomalachite, cerussite, alunite
, jarosite, plumbojarosite, osarizawaite, plumbogummite, duftite, mimetite, fornacite, wulfenite, mottramite, iodargyrite, native silver and a silver-mercury amalgam.
Drill target delineation and prioritization are based on critical technical characteristics which include a varying combination of a magnetic inversion low anomaly (possible magnetite destruction), silica and clay alteration (particularly high temperature clays such as alunite
& advance argillic facies), permeable/reactive volcanic host rock or possible structure, prominent topographic linear, coincident surface soil-rock geochemical anomalies, nearby anomalous historical drill hole results and proximity to the Pueblo Viejo property's concealed Arroyo Hondo exploration target.
The Azerbaijan Industrial Corporation (AIC) has announced a tender for the selection of economically viable, environmentally friendly technologies, holding relevant laboratory and industrial tests, as well as preparing detailed feasibility study for obtaining the necessary concentrate of alunite
, alumina and other semi-finished mineral products by alunite
processing,Trendreports with reference to the AIC.
