Various analyses of physico-chemical characteristics and batch tests were conducted with the sludge obtained from a full-scale electrolysis facility for treating coal mine drainage in order to find the applicability of sludge as a material for removing Zn(II) in an aqueous phase. The physico-chemical analysis results indicated that coal mine drainage sludge (CMDS) had a high specific surface ar...

Modelling the reservoirs and fluxes of Zn in Earth's crust mantle requires data on solubility its mineral hosts ores coexisting fluids, as well complexation these fluids a function fluid composition, pressure, temperature. However, due to experimental challenges, availability such is limited pressures below 1 GPa, which are only representative upper conditions. Here, we report effects salinity ...

Abstract Carbonate minerals play a dominant role in the deep carbon cycle. Determining high-pressure and high-temperature vibrational properties of carbonates is essential to understand their anharmonicity thermodynamic under crustal upper mantle conditions. Building on our previous study aragonite, calcite (both CaCO3 polymorphs), dolomite [CaMg(CO3)2], magnesite (MgCO3), rhodochrosite (MnCO3)...

Gardaneshir Pb–Zn deposit is hosted by dolomitic carbonates which is located in the SW Ardestan, central Iran. Ore body is stratabound type in this deposit. Primary ores in this type are composed of sphalerite, galena, barite and quartz with massive, banded, veined and disseminated structures. Evaluation of ore-grade at the Gardaneshir Pb-Zn deposit, based on chemical analysis which indicates a...

Clustering methods unequivocally show considerable influence on many recent algorithms and play an important role in hyperspectral data analysis. Here, we challenge the clustering for mineral identification using two different strategies long wave infrared (LWIR, 7.7–11.8 ?m). For that, compare to perform a unique dataset. The first algorithm uses spectral comparison techniques all pixel-spectr...
